摘要

在传统的有源滤波器中，检测负载电流以及有源滤波器的输出电流。然后，提取负载电流的谐波分量，形成有源滤波器的参考电流。本文提出了一种只需检测源电流的新型电流控制方法。它既不需要检测有源滤波器的输出电流，也不需要从源电流中提取谐波分量。仅需要两个电流传感器来检测各自两相的电流。这样，可以大大简化当前的控制系统。

A current control method for active filters without detecting current harmonics

In conventional active filters, the load current as well as the active filter output current is detected. Then, the harmonic component of the load current is extracted to create a reference current of the active filter. This paper proposes a novel current control method that requires only detecting the source current. It requires neither detecting the active filter output current nor extracting a harmonic component from the source current. Only two current sensors are required for detecting the current in respective two phases. Thus, the current control system can be greatly simplified.
