In this paper a high step-up interleaved boost converter is proposed for renewable energy applications. The proposed converter uses multi-phase/interleaving technique with two coupled inductors in one phase and an intermediate capacitor between the two phases. The idea is such that the coupled inductors are used to develop a high voltage across the intermediate capacitor and then this high voltage...
Shunt Active Power Filter (APF) is a good solution to eliminate current-type harmonics generated by nonlinear load. Challenges exist in realization of large power and high compensation precision simultaneously due to the limited capacity of semiconductor devices, thermal management, high slew rate of compensation current, low switching frequency and phase lag of digital control loop etc. This paper...
Shunt Active Power Filters (APF) have been proved useful to compensate current harmonics in power grids. In traditional shunt APF, the passive filter, which serves as the output filter, is usually using uncoupled inductors. In this paper, the coupled inductors are adopted in place of traditional uncoupled ones. And both the equivalent circuit and the coupled inductor's selecting principle are given...
