Zero-Voltage Zero-Current Transition Network for Dual-Phase Interleaved Converter
Jyoti Prakash,Mummadi Veerachary +1 more
TL;DR: In this paper, a zero-voltage zero-current transition scheme suitable for a family of dual-phase interleaved converters is proposed, where the auxiliary transformer self-adjusts the current in the auxiliary network depending upon the loading conditions and thus the reactive energy during the soft switching is low for the entire range of loads.

Mummadi Veerachary,B. Amarendra Reddy,E. Vargil Kumar +2 more
- 01 Dec 2012
TL;DR: In this paper, a two-input DC-DC converter suitable to draw power from two different dc sources feeding a common DC-bus is presented, where both the sources either individually or simultaneously supply power to the downstream load at reduced ripple current.
