In a non linear environment SAPF can used to compensate harmonics and reactive power efficiently. The Dynamic performance of SAPF mainly depends on the controller used to extract the harmonic content in source current. Most of the control techniques are require number of complex transformations. In this paper a simple and easy to implement synthetic sinusoid generation technique by sensing the load current is proposed. The working of proposed controller is verified at different load conditions.
