Abstract

This paper presents an OTA-based control system of active power filter for harmonic and reactive power compensation in power system. An SCR-full wave rectifier is used as an uncontrolled nonlinear load. A single phase control of shunt-VSI-APF is discussed for simplicity. This proposed OTA-based control circuit has the advantage of self-tuning, low cost, simple and small size circuitry compared to the use of high precision multiplier or digital processor. Theoretical analysis, design and simulation results of the OTA-circuit are provided. A prototype is being developed to demonstrate the performance of the control system.
