Design and Control of a Three-Phase T-Type Inverter using Reverse-Blocking IGBTs

This paper proposes the design and implementation of a 15kW three-phase T-type inverter. Fuji Electric's new generation IGBT module (V series) using RB-IGBT technology is applied for converter, due to its higher efficiency from conventional IGBTs reduce switching losses on semiconductors. Under full load conditions, overall converter can reach over 98%. The control sine PWM modulation are implemented DSP kit named TMS320F3F28379D. In addition, generated with fundamental third harmonics sin wave, allowing factor up 1,154 compared traditional PWM. output voltage 220V/50Hz less than 2% THD be achieved at minimum input DC 550V.
