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 by C.W. Lander (1993) is discussed for simplicity. This proposed OTA-based control circuit according to T. Deliyannis et al. (1999), E.W. Greeneich (1997) and on www.national.com 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 developed to demonstrate the performance of the contol system according to R.C. Dorf and R.H. Bishop (2001).
