Abstract
A new non-isolated ZVS self-driven current tripler topology for high current and low voltage applications is proposed in this paper. The most important advantage of the proposed topology is reduced current stress and conduction losses of the synchronous rectifier (SR) MOSFETs and transformer windings, which is beneficial for high current applications. Other features of the proposed topology are: 1) duty-cycle extension; 2) ZVS of all the control MOSFETs; 3) reduced voltage stress over the SRs and reduced reverse recovery loss; 4) gate energy recovery of SRs and no external drive IC with the dead time control needed. A 12V input, 1.0V/50A output, 1MHz prototype was built to verify the advantages of the proposed converter.
