摘要
主变压器偏磁现象是电压源型全桥变换器的主要问题之一。提出基于峰值电流检测偏磁抑制技术,确保施加在初级绕组上的正、反两个方向电压伏秒面积相等,从而消除偏磁。详细描述了基于峰值电流检测偏磁抑制技术的工作原理及其电路组成,实验结果验证了峰值电流检测偏磁抑制技术的正确性和有效性。
The biasing magnetic phenomenon of the main transform is one of main issues on voltage source full-bridge con-verter.Based on the peak current detection biasing magnetic suppression technologyt,o ensure volt-second area is equal to the positive and negative voltages in both directions on the primary side windingt,hereby eliminating the bias magnet.The working principle and circuit based on peak current detection magnetic biasing suppression technology are described in de-tail.The experimental results verify the correctness and effectiveness of the peak current detection bias magnet suppression.
