This study deals with photovoltaic power plant modelling and its integration within the distribution network. It presents a simulation model of a whole photovoltaic power plant including the solar cells, boost converter with maximal power point tracking, voltage-oriented control and inductor-capacitor-inductor (LCL) filter. In such a sense, the applied inverter has many advantages such as a controllable...
The paper presents a single-stage high-power-factor electronic ballast for metal halide lamps. The proposed ballast integrates a buck-boost converter, a buck converter and a full-bridge inverter into a single power conversion circuit. The buck-boost converter served as a power-factor corrector (PFC) is designed to operate at discontinuous conduction mode (DCM) to achieve nearly a unity power factor...
This paper presents one of the methods to improve a input current waveform of a neutral point type step-down converter circuit which we developed before. A neutral point type step-down converter circuit shares switching devices with half bridge inverter, and it is the circuit which can constitute an electronic ballast of a one converter method. A neutral point type step-down converter circuit has...
