Bidirectional high conversion ratio DC-DC converter

Bidirectional high conversion ratio DC-DC converter

Recent trends in power conversion indicate a need for dc-dc power conversion at very high power levels and with high voltage buck/boost ratio for transmission/distribution purposes. No single conventional topology is well suited to these constraints. This paper proposes a new buck- or boost-derived...

Zusammenfassung:Recent trends in power conversion indicate a need for dc-dc power conversion at very high power levels and with high voltage buck/boost ratio for transmission/distribution purposes. No single conventional topology is well suited to these constraints. This paper proposes a new buck- or boost-derived multilevel non-isolated converter with superior scaling abilities. The paper derives the dynamic model in state space form, presents a suitable modulation method, and validates findings with computer simulations in MATLAB/Simulink and PLECS.
