New Intelligent Semiconductor Transformer With Bidirectional Power-Flow Capability
IEEE Transactions on Power Delivery, 2014This letter proposes a new intelligent semiconductor transformer (IST) which consists of a bidirectional ac/dc resonant converter, dc/dc converter, and dc/ac converter. This structure provides good voltage-balancing performance on the high-voltage side and a simple control method for bidirectional power flow.

Unified stability criterion of bidirectional power flow cascade system
2013 Twenty-Eighth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2013The stability issues of cascade system have been studied for many years. Some classic criterions in the form of Zo/Zi like Middlebrook criterion has been proposed and the validity have been proved in the case like voltage source with a current sink. But they meet the challenge in some application, especially in the case of current source with voltage ...

A novel square-wave converter with bidirectional power flow
Proceedings of the IEEE 1999 International Conference on Power Electronics and Drive Systems. PEDS'99 (Cat. No.99TH8475), 1999A novel ZVS phase-shift controlled bidirectional DC-DC convertor is proposed. It possesses the conventional features of phase-shifted convertors, including constant switching frequency, zero-voltage switching (ZVS) and voltage control by phase-shift. However, the new convertor has been improved by developing a bi-directional power flow capability and ...
