Optimized Reactive Power Control of Module Power Imbalance of Cascaded Converter
IEEE Open Journal of Power Electronics, 2022 In the medium voltage cascaded converter, the power imbalance problem among the converter modules will result in certain converter modules over-modulated. Reactive power control (RPC) scheme is an effective way to balance the cascaded converters.
