Abstract: This article describes a PWM inverter based shunt active filtering scheme for high frequency AC systems in space applications. A relatively simple control architecture using only proportional, integral, and resonant controllers along with a sec-ond order generalised integrator is proposed for the shunt filter. The controllers are designed such that they are implementable using Op-Amp based analog circuits which is preferable for space application. Example design parameters are given for designing the analog controllers. Simulation results are shown to compare the performance of the proposed system with classical passive filter based compensation. Dynamic response of the proposed system due to load change is also shown.
