Coordinated Control of Second-Order Harmonic Voltage and Current Fluctuations in Cascaded H-Bridge Inverter with Supercapacitor and DC-DC Stage at Variable Output Frequencies

Coordinated Control of Second-Order Harmonic Voltage and Current Fluctuations in Cascaded H-Bridge Inverter with Supercapacitor and DC-DC Stage at Variable Output Frequencies

In the cascaded H-bridge inverter (CHBI) with supercapacitor and dc-dc stage, inherent second-order harmonic power flows through each submodule (SM), causing fluctuations in both the dc-link voltage and the dc-dc current. There exist limitations in handling these fluctuations at variable output freq...
