摘要
分析了两级式低电压大电流电路拓扑结构、工作原理及控制特性。由于该类逆变器采用前级调节,所以稳定性差、动态响应速度慢。为此,结合其结构特点,提出了电压双环控制方案。仿真与实验结果表明,该控制方案具有良好的控制效果。
The topologies,principles and characters of the two-stage low voltage/high current converters are analyzed. Due to the high grades of the mathematic model and the use of the preregulators,the stability and the dynamic response of this converters should be opetimized.Here a double-voltage-loop control strategy is presented.Simulation and experiment results validate the goodness of this new control strategy.
