Dynamic Response Improvements of Parallel-Connected Bidirectional DC–DC Converters for Electrical Drive Powered by Low-Voltage Battery Employing Optimized Feedforward Control

Parallel-connected modular current-fed bidirectional dc-dc converters are used for the AC motor drive system powered by batteries with low voltage and wide voltage range. The input current ripple can be reduced significantly by employing interleaving technology not only for individual module but als...
