Popis: SGS20/164/OHK3/3T/13 The current collapse phenomenon increases conduction losses in high electron mobility transistors. This paper presents a simple option to decrease these losses in 3 phase hard-switching inverter driving permanent magnet synchronous motor utilizing 5-segment SVPWM modulation. Converter DC-link input power decrease by 2 % was observed compared to classic 7-segment modulation. This decrease results in significant decrease of transistor operating temperature.
