This study analyzes the turn-on and turn-off transients of a metal-oxide-semiconductor field-effect transistor (MOSFET) with high-
switching frequency systems. In these systems, the voltage distortion becomes serious at the output terminal of a Vienna rectifier by
the turn-off delay of the MOSFET. The current has low-order harmonics through this voltage distortion. This paper describes the
transient of the turn-off that causes the voltage distortion. The algorithm for reducing the sixth harmonic using a proportional-
resonance controller is proposed to improve the current distortion without complex calculation for compensation. The reduction of
the current distortion by high-switching frequency is verified by experiment with the 2.5-kW prototype Vienna rectifier.
