Fast switching converters based on GaN devices and resonant architectures (IP-2019-04-8959)

- project FASCON ( (2020 - 2024) 

- funded by: Croatian Science Foundation (Croatia)


Switching converters are very important in modern electronics because of their high efficiency in portable applications and in automotive electronics. This project aims to provide the methods for the reduction of the generated electromagnetic (EM) interference of the resonant converters while keeping their high efficiency. Several approaches are analyzed. Utilization of a spread-spectrum technique improves electromagnetic compatibility (EMC), but it may deteriorate other characteristics of the converter, e.g. the efficiency. The spread-spectrum modulation in commercially available converters is usually fixed and its parameters are not user-configurable. Having a configurable spread-spectrum modulator allows fine tuning and reduction of generated EM emissions without having to sacrifice the performance. Secondly, using gallium-nitride (GaN) transistors in switching power converters instead of silicon ones leads to lower power losses and operation of the converters at even higher switching frequencies. Thirdly, the investigation on the impact of the voltage conversion ratio on power efficiency and electromagnetic emissions in the high-frequency multi-stage DC-DC converter chain is performed. Finally, measurements of switching converters are very demanding, firstly because of the measurements of the high side transistors and secondly because of strong conducted and radiated electromagnetic emissions. In this project, an entire electro-optical measurement environment for characterization of electromagnetic compatibility and measurement of transistor switches is developed and its usage is fully assessed from the viewpoint of technical specifications and commercial usefulness. The proposed research investigates the methods for optimization of power efficiency of switching power supplies while meeting the acceptable levels of electromagnetic emissions using novel device technologies and architectures of DC-DC power converters.

Advanced design methodology for switching DC-DC converters

- project AdvaDCDC ( (2015 - 2019) 

- funded by: Croatian Science Foundation (Croatia)


Advanced design methodology for switching DC-DC converters is developed in this project. The low-side and high-side switch, their drivers and the control circuitry are integrated into one package which minimises the parasitic elements and allows switching frequencies up to 10 MHz. A driving-signal circuitry with high-precision adjustable timings is developed. This will allow the optimisation of dead-times with respect to the power conversion efficiency of a converter for any given set of the parameters of the integrated circuit (IC) package, external components and a printed circuit board (PCB). A special attention is given to the design of a level-shifter for a high-side switch. Besides driving the on-chip power switches, the developed driving-signal circuitry is routed to external pins of the IC package to enable driving of the externally connected switches.

Gallium-nitride (GaN) and silicon-carbide (SiC) semiconductor devices present a promising solution for a high-voltage and high-efficiency power conversion. In order to design a highly efficient converter for high-voltage switching applications by using GaN and SiC power transistors, the GaN/SiC DC-DC converter will be optimised by using adjustable driving-signal circuitry, which is designed at the beginning of the project. The developed methodology will allow the evaluation of the efficiency of GaN and SiC devices in high-voltage switching applications as well as highly optimised design of the converters.

The PCB, on which the converter IC is soldered, represents the next crucial part of the design and it has a dominant effect in determination of the electromagnetic compatibility and thermal properties of the converter. A simulation environment which will allow the electromagnetic-thermal co-optimisation of DC-DC converters will be developed. A statistical analysis of the parameters of a PCB and an IC package will be performed to ensure that the variations in the manufacturing process do not compromise the reliability and the efficiency of the designed converters.

The accuracy of design and modelling of DC-DC converters will be improved by accurate modelling of power inductors under realistic operating conditions (signal shape, current levels, self-heating) and by performing electromagnetic compatibility measurements and modelling, which is always required by industrial partners.

- project IntRFID ( (2014 - 2016)

- main partner: Locus d.o.o., Zagreb (Croatia)

- financed by: European Union through the European Regional Development Fund via Ministry of Science Education and Sports (Croatia)



This project aims to develop the key building blocks for the integrated circuits which are the basis for the development of applications for wirelessly powered distributed sensor networks. For this project circuit development and chip processing are based on a 0.18 μm CMOS technology. Today's sensor nodes in distributed networks use the battery supply, which is problematic due to the limited battery life time and its cost.

Integration of wirelessly powered supply with data processing circuits inside a single chip is a solution which simplifies the functionality and the maintenance of the sensor networks. In this project chip is processed as a system consisting of the circuits for the wireless supply, the analo-gue-to-digital converter, the oscillator and the communicaƟon channel. The main goals of the project are to bring research and development activities and innovation closer to the needs of the Croatian industry, build capacities of the academic institutions and the public science institutions for the technology transfer, better cooperation with the industry and to uplift the environment for the research,  development and innovation through infrastructural investments and investments in the necessary research equipment. 

Core research activities on the project include the development of the wirelessly powered supply, the development of a 9-bit cyclic analogue to digital converter insensitive to the variations of the power supply voltage, the development of the oscillator insensitive to the variations of the power supply voltage, the development of the communication channel, the measurements on the processed chips and the dissemination of the research results.

Intelligent light Management for OLED on foil Applications

- IMOLA, FP7 project ( (2011 - 2015)

- main partners: imec (Belgium), TNO (The Netherlands), Philips (Germany), NXP (The Netherlands), NXP (Belgium), Hanita (Israel), Henkel (Belgium), CRP (Italy), Fundico (Belgium)

Project Objectives: 

The main objective of the IMOLA project is the realization of a large-area OLED-based lighting module with built-in intelligent light management. Interesting applications are wall, ceiling and car dome lighting, where the light intensity can be adjusted uniformly or locally according to the time of the day or the position of a person, or even road lighting, where the light can follow a car.

The front side of the module consists of OLED tiles attached and interconnected to a flexible backplane foil. In an early stage of the project, individual tiles (on glass as well as on foil) will be used, but in a later stage OLED tiles on the roll will be laminated and interconnected to the backplane.

The backplane of the module contains the integrated driver electronics for the brightness control of the individual OLED tiles. A very thin and efficient smart-power chip converts a single 40V supply voltage into a controllable DC current for each OLED tile. This power converter chip employs an external passive component (inductor) that will preferably be embedded into the backplane foil. As the smart-power chip also allows the integration of dense CMOS circuitry, extra functionality and intelligence can be implemented on the chip. This includes optical feedback to eliminate non-uniformities between the tiles or to compensate OLED degradation effects. Other sensor functions can provide maximum interaction with the environment. Furthermore, advanced communication features, e.g. by means of PLC techniques across the power supply lines, can enable intelligent brightness control from a central unit.

Within the consortium, all necessary expertise is available to ensure perfect coverage of all technological aspects (such as OLED and backplane foil development, chip placement, electrical interconnect, component embedding and lamination) as well as all design aspects (driver chip design, inductor design and EMC) in this challenging project.

Smart power circuits and technologies contribute in a unique way to the realization of the system-on-chip concept by combining digital logic with analogue signal processing and power and high voltage switching. The main objective of this project is to enable a robust design of smart power circuits leading to a first-time-right design with built-in reliability and thus avoiding very costly over-dimensioning. To achieve this ambitious goal, compact models will be built that accurately describe power device operation including extensions to verify safe-operating area conditions. The devices to be modelled include the lateral DMOS, vertical DMOS and LIGBT fabricated in bulk silicon and power devices realized in advanced SOI technology.Model extensions are planned for device ageing due to hot-carrier injection, statistics due process variations, device matching and layout effects such as large area closed-cell matrices. An important feature will be an accurate description of the internal device temperature plus a coupling to package thermal models and EMC modelling. The final goal is to achieve a system level design flow for smart-power SoC using complex transistor level simulations or generated black-box models. Full smart power circuits will be simulated with the new design flow and models will be assessed and calibrated against experimental measurements. The gain in performance and robustness will be quantified. The project therefore aims at providing the EC "power" industrial community with new, highly robust tools to design and characterize smart power devices and circuits. This will strengthen and significantly advance ECs position as a fast growing, world supplier of smart power technologies. Design and fabrication of highly reliable and efficient Smart Power circuits is one of the most important strategic ways to reduce drastically energy losses in power systems by ensuring optimal energy conversion at all times.
