Abstract

This paper describes a newly developed power conditioner with variable current loop gain. The power conditioner consists of a do-link capacitor and three phase inverter with coupled inductor. This system is very well operated to compensate current harmonics and asymmetries caused by nonlinear load and unbalance loads. The power conditioner shapes the source current sinusoidal in phase with source voltage. A 100kVA power conditioner was built and the controller is realized with DSP Experimental results for many load conditions are presented to verify the performance of the controller.
