| Abstract: | Based on input-series and output-parallel(ISOP) converter and multiple output flyback converter,a kind of auxiliary power supply applicated to high power system is proposed.In the proposed scheme,a new control method with primary side current feedback is presented,so it ensures input voltage sharing and output current sharing of the modules among the ISOP converter,improves the degree of isolation between primary side and secondary side,and e-liminates the opto-coupler from the circuit.Some problems of the ... |
