ANALYSIS AND DEVELOPMENT OF HIGH PERFORMANCE ELECTRONIC CONVERTERS WITH WIDE BAND GAP DEVICES

Existing common technologies, based on the use of silicon electronic devices, have low thermal limits and limits in maximum working frequency. Over the last few years, we have witnessed the development of new state-of-the-art power electronics, called Wide Band Gap (WBG), able to overcome these limitations. The use of WBG devices is bringing benefits in terms of performance and is becoming a universal solution in all power electronics applications. The goal of the research project is to analyze and study innovative power electronic converters using WBG devices to achieve higher efficiency values than 99%, and to achieve a increased power density in terms of volume and weight.

Further insights on a converter realized in the previous academic year, are carried out using advanced tools that allow to extrapolate the parameters intrinsic parasites of the layout with the aim of studying the hot spots of a power converter.The simulation estimate allows to obtain a real pseudo converter model that allows efficient design of power boards. These results are more suited to converters that use widebandgap devices because the high frequencies of communication bring the design of the pcb an extremely critical part of the design.

The goal is to analyze various bidirection converter topologies to obtain an overview that allows you to choose the topology that adapts to the specifications of costs and performance.The analysis focuses on the estimation of efficiencies, obtaining results that also allow us to choose the device that best suits the application. The predetermined future development is to use this information for the realization of power converter modules 2LC 3LNPCC 3LTTC

I-MOSFET and SIC-MOSEFT IGBT-based technologies have been considered in the analysis

We are developing a prototype three-phase bidirectional power converter based on SiC devices with the aim of creating a high performance system. The control of this system has been implemented on a new generation microcontroller that integrates high performance peripherals.The implemented structure integrates a sophisticated Decoupling current control based on vector control.The objective is to obtain a control with a high execution task that can make the most of the high switching frequency.
