| Abstract: | In this paper, voltage loop and peak-value current loop are used to control a high power DC/DC converter, one strategy to eliminate the transformer magnetic bias is proposed, 3 kW push-pull converter is designed and MATLAB verifys the strategy of eliminating the transformer magnetic bias. This strategy has already used in some converter with low voltage input. |
