摘要
An internal parallelization based active neutral point clamped (IP-ANPC) converter is provided having a low switching frequency (LSF) part and a plurality of high switching frequency (HSF) modules. The HSF modules are connected in parallel and the converter is modular. The converter provides the benefits of modularity, improved reliability and efficiency, interleaving operation, and reasonable utilization of wide band gap (WBG) devices. A logic based flying capacitor voltage balancing scheme is also provided. The balancing scheme includes naturally balancing the voltage of the converter with phase shift pulse width modulation and redundantly balancing the voltage of the converter with redundant switching states.
