To solve the above problems, a novel resonance injection type hybrid active power filter is presented, it allows the energy exchange between the DC-side capacitor and grid, DC-side voltage will be stabilized after the proposed control method base on the regulation of reactive current is adapted. On the other hand, a new current control method is proposed which is based on the control of error between injection current and harmonic current compensated by passive power filter using recursive PI.

在此基础上结合提出的基于基波无功电流闭环调节的直流侧电压控制方法，保证了直流侧电压的稳定；提出了采用递推积分将无源滤波器作用后电网谐波电流与注入支路补偿电流进行闭环比较控制以获得参考电流的方法，减小了误差，提高了系统的控制精度。
