Although #Gallium #Nitride (#GaN) Field Effect #Transistor (#FET) devices have found extensive application in DC-DC converters, their utilization in inverter #motor #drives remains an evolving area of study. In particular, the intricacies of reverse conduction operation during the dead time, specific to GaN FETs, require in-depth exploration for inverters supplying AC currents to electrical motors. Therefore, this paper undertakes an assessment of reverse conduction during the dead time intervals in low-voltage GaN FETs employed in motor drives applications. This analysis provides correlations between device technology attributes and the variations in AC phase current. To facilitate this investigation, a dedicated numerical tool is developed to evaluate the reverse conduction characteristics of GaN FET and associated power losses. Furthermore, this study includes a comparative analysis of the reverse conduction behavior of GaN FET devices with their low-voltage #MOSFET counterparts, taking into account their differing static and dynamic characteristics. As a result, the main contribution of this work is to provide to the inverter designers a comprehensive understanding of dead-time effects in GaN-based inverters, along with guidance on selecting and optimizing dead time intervals within inverter legs for motor control applications employing the latest generation of GaN FET devices.

Politecnico di Torino develops SyR-e, a MATLAB-based development platform for electric machines and drives, allowing you to design various types of synchronous motors, including reluctance, surface PMSM and internal PMSM. SyR-e is integrated with FEMM for finite element simulations. It also integrates both semi-analytical design procedures and a multi-objective optimization algorithm (MODE). SyR-e is able to automatically generate a Simulink-Simscape model. All inputs relating to design, analysis, materials and windings are chosen from a graphical interface developed with MATLAB App Designer. Many compliments for this remarkable platform to prof. Gianmario Pellegrino, Simone Ferrari, Paolo Pescetto and Andrei Bojoi. All the code is available on MATLAB File Exchange and GitHub.
