This paper presents a new conceptual circuit topology of a high efficiency single-phase sinewave PV power conditioner with a compact intermediate film capacitor DC link stage. It consists of time-sharing partial sinewave absolute pulse width modulated boost chopper with auxiliary bypass diode in the first power processing stage and time-sharing partial sinewave pulse width modulated polarity changing...
This paper describes a high-frequency ZVS-PWM chopper-fed DC-DC power converter with a single active auxiliary edge-resonant snubber in the load side which can make use of the pre-regulator of the small scale power conditioners such as solar photovoltaic generation, fuel cell generation, new type rechargeable battery and super capacitor energy storages. Its principle operation in steady-state is described...
In this paper, a novel proposal of the utility-interactive three-phase soft commutation sinewave PWM power conditioner with an auxiliary active resonant DC-link snubber is developed for the fuel cell and the solar power generation systems. The prototype of this power conditioner consists of a PWM boost chopper cascaded three-phase power conditioner, a single two-switch auxiliary resonant DC-link snubber...
This paper presents a novel circuit topology of a high efficiency single-phase power conditioner. This power conditioner is composed of time-sharing sinewave absolute pulse width modulated boost chopper with a bypass diode in the first power processing stage and time-sharing sinewave pulse width modulated full-bridge inverter in the second power processing stage operated by time-sharing dual mode...
