To increase the capacity of the active power filter, a novel transformer structure with multiple compensationwinding is proposed.
这种有源电力滤波器的大容量通过变压器二次侧多绕组结构来实现。

Therefore, the proposed structure could satisfy the demands of large-capacity systems because each compensationwinding has a low demand to the current amplifier.
因此，每个补偿绕组对补偿电流放大器的容量要求较小，从而满足了系统大容量的要求。

The harmonic compensation currents proportional to the harmonic current in the primary winding, which is detected real-timely, are injected to the multiple secondary winding of the transformer.
