Feed-Forward Control of Input-Series and Output-Parallel DC Transformer

Abstract:

The input-series and output-parallel (ISOP) DC transformer, which has no output filter, runs under near 100% duty ratio, and is easily achieve zero voltage switching (ZVS) conditions and higher efficiency, is more and more attractive in the high input voltage and high power applications. In order to achieving input voltages sharing in ISOP DC transformer based on two non-resonant DC transformer modules, the feed-forward control method is proposed in this paper. And the principle of the proposed control is analyzed in detail. Finally, experimental results are given to verify the proposed control method to have a good ability of sharing the input voltages.
