Control and design of a four-switch inverter with reduced low-frequency input current ripple and capacitance requirement: A comparative study

A large amount of ripple at twice the output frequency will emerge in the input current at dc side due to the pulsating output power in a single-phase dc-ac power conversion system. In this paper, a current-source-type four-switch inverter based on switch multiplexing technique is studied, which can realize the reduction of input low-frequency current… CONTINUE READING
