RC-qTPWM method with high DC voltage utilization ratio …
Three-Phase Chb Inverter TopologyDC Voltage Utilization RatioPower Balance and The Rc-Qtpwm MethodIn this paper, the power balance is defined as equal to the average output power of each H-bridge unit in a single-phase inverter. The PD-qTPWM method shown in Fig. 5 can be obtained by using vq as the modulation wave of the PD-PWM method. vc1±, vc2±, and vc3± are the carriers of the H-bridge unit i (i = 1,2,3), respectively. Under the PD-qTPWM met...See more on link.springer ResearchGate[PDF]
