A single-stage power converter for dc uninterruptible power supply (UPS) is proposed in this paper. Basically the proposed converter is an integration result of a power factor correction circuit with a dc-to-dc converter to achieve simple hardware circuit, high efficiency, and low cost for extra UPS function. Under normal operation, a two-switch CUK(More)
A high performance three-phase active power filter is proposed in this paper. A novel circuit for detecting the amplitude of the active part of the fundamental load current is also proposed. The detection time of the current is not more than 1/4 cycle. Its transient response is superior to the other conventional techniques. Moreover, the proposed algorithm(More)
