Implementation of Shunt Active Power Filter Based on a Simple Novel Control Algorithm

Shunt active power fi lter are commonly used as a harmonic and reactive power compensator. In this paper, a simple control method is described to control shunt active power fi lter. It operates on constant switching frequency, hence switching losses and stresses on the devices are lower. It can compensate the reactive power required by the load without sensing and computing the associated reactive power component, thus control circuit is made simple. It can also compensate harmonic components of the non-linear loads. The experimental results are agreed with the analytical and simulated results.
