The Analysis of Switching Losses of IGBT with RPWM Control

Caihua Yi,
Jiaqing Ma,
Gangqin Wu
et al.

Abstract: When the random pulse width modulation (RPWM) technique is applied to insulated gate bipolar transistor (IGBT) modules, the switching losses are decreased to different degrees. In order to study the principle of this control method, this paper starts from the perspective of Joule heating principle. According to the energy losses and heating characteristics of IGBT module during on-state and off-state processes, the effects of different random pulse width modulation (RPWM) techniques on the switching losses of … Show more
