Versatile Control of Unidirectional AC–DC Boost Converters for Power Quality Mitigation

摘要: This paper introduces a versatile control scheme for unidirectional ac–dc boost converters the purpose of mitigating grid power quality. Since most factor correction circuits available in commercial market utilize converter topologies, this is an almost no-cost solution compensating harmonic current and reactive residential applications. Harmonic compensation methods are investigated. The additional focus to quantify input distortions by used supplying not only active load but also power. Due distortions, amount injected from individual should be restricted. Experimental results presented validate effectiveness proposed method.
