摘要
利用了电压环和峰值电流环控制大功率推挽DC/DC变换器,提出消除主变偏磁的策略,设计了3kW推挽变换器,利用MATLAB仿真验证了该控制策略可以消除主变偏磁。该策略已用于低压大功率的变换器。
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.
