摘要
针对间接电流控制的缺点,通过引入电流解耦控制器来补偿相位,根据判断功率因数的值,以分段式非线性的控制策略改变补偿系数,从而稳定、快速地降低交流侧电压和电流的相位差,提升功率因数。
In the light of the defect of traditional indirect current control strategy,the use of current decoupled controller is proposed to compensate for phase.According to the value of power factor,the compensation coefficient is changed by means of piecewise nonlinear control strategy,so that the phase difference between voltage and current in AC side can be reduced steadily and rapidly,and the power factor can be raised.
