This paper proposes modulation and control strategy for a single-phase to three-phase (1p-3p) indirect matrix converter (IMC) drives. The 1p-3p IMC is composed of a singlephase current source rectifier (1p-CSR) and a three-phase voltage source inverter (3p-VSI). The 3p-VSI is operated with modulation strategy similar to that of a common inverter. The 1p-CSR must be operated with a restriction where...
This paper proposes a discontinuous pulse width modulation (DPWM) method for an indirect matrix converter (IMC) driving induction motor (IM) in order to reduce switching losses. The IMC has advantages that long lifetime and reduced volume depending on the lack of capacitors. However, the IMC has many electric switching devices because it is composed of two stages such as a rectifier stage and an inverter...
This paper proposes a three-phase input indirect matrix converter topology for a dual ac-drive system with modified switch control schemes, along with addition of a leg. This topology is developed based on a very sparse matrix converter with addition of a leg in the inverter stage, which can reduce the amount of power transistors compared to the conventional dual matrix converter system and; therefore,...
