Indirect matrix converters (IMC) offer high efficiency, high power density, and bidirectional power flow capability with single-stage three- to single-phase AC-AC power conversion integrating a three-phase active rectifier with a primary side full-bridge inverter of a dual active bridge converter. However, IMCs usually require space vector modulation, with complex calculations. This paper proposes a simple and robust carrier-based pulse width modulation (PWM) technique using a voltage-source inverter (VSI) to IMC translation. This translation allows conventional VSI control with active and reactive power control with carrier-based techniques. The VSI vectors are matched with current-source inverter (CSI) vectors and translated to IMC modulation signals. Nine carrier waveforms are proposed, and grid current THD and efficiency are estimated. The symmetric A and B methods had the lowest THD of the grid current, 2.80%, and the efficiency remained at approximately 98.3%, making it the most suitable carrier-based method proposed in this paper. The space vector PWM (SVPWM) modulation method was implemented to the DSP and generated the expected twelve gate signals.
