Abstract:

This paper introduces the Hybrid Active Power Filter (HAPF) for power-factor correction, harmonic reduction and current compensation. The existing control scheme was implemented without load harmonic detection. In a hybrid active power filter(HAPF), the active part is used to filter out the higher order harmonics, while lower order harmonics are eliminated by passive filter tuned for 5th and 7th order harmonic frequencies. The compensation constraints are obtained by regulating the currents indirectly from the power mains. The reference currents of SAPF are generated by the dc-link voltage controller based on the active power balance of system. A high step-up converter, which is suitable for renewable energy system, is proposed in this paper to produce a dc-link voltage. Through a voltage multiplier module composed of switched capacitors and coupled inductors, a conventional interleaved boost converter obtains high step-up gain without operating at extreme duty ratio. Experimental results are shown for determining the effectiveness of the solar energy harvested HAPF-proposed control system.
