This paper presents a discontinuous pulse width modulation (DPWM) method to reduce switching losses in an indirect matrix

converter (IMC) drive. The IMC has a number of power semiconductor switches. In other words, it consists of a rectifier stage and an

inverter stage for AC/AC power conversion, which are composed of 12 and 6 switching devices, respectively. Therefore, the switching

devices of the IMC suffer from high switching losses in the IMC drives. Various topologies to reduce switching losses have been

studied by eliminating a number of switches from the rectifier stage. In this study, in contrast to prior research, a DPWM method is

presented to reduce the switching losses of the inverter stage. The effectiveness of the proposed method to reduce switching losses

in IMC drives is verified by simulations and experimental results.
