- Description
- In PWM converters, current ripple is inherently produced by the switching actions. The current ripple would then introduce oscillating power which reduces the efficiency of the system. This paper proposes a new Phase-Shifted Carrier PWM technique for the Multilevel Cascaded H-bridge converter, which employs Carrier Phase Angle Offset to achieve cancellation in the current harmonics. Thus reducing the oscillating power delivered to the load. The mathematical analysis of the proposed modulation technique is presented and shown to provide an significant improvement over the conventional PSC-PWM. Simulation and experimental results are also provided to verified the theoretical analysis.
