介绍一种用功率守恒的方法近似代替负载电流前馈控制中的直流侧电流,不但能达到与之类似的效果,而且去除了直流侧电流传感器,降低了成本,仿真验证说明了本方法的有效性。
A method of conserving power is introduced to replace the DC current in the load current feedforward control, which can not only achieve the same result, but also remove the DC current sensor and reduce the cost. The simulation results show that the method is effective Sex.
