Abstract: A single stage electronic ballast with power factor correction is provided. The single stage electronic ballast can work under the present intensity discharge lamp without any change and provide higher efficient, lower power consumption of lighting system, and better lighting quality of lamps. The single stage electronic ballast can also provide a stable current to load (lamp) for a long time. The single stage electronic ballast includes a first switch and a second switch that are controlled with complementary switching so as to provide an output voltage in response to the input power source and the variation of the load.

Abstract: An inverter with soft switching is used for a high step-up ratio and a high conversion efficiency. The inverter includes an isolation voltage-quadrupling DC converter and an AC selecting switch. The isolation voltage-quadrupling DC converter includes an active clamping circuit. By a front-stage converter circuit, a continuous half-sine-wave current is generated. By a rear-stage AC selecting switch, the half-sine-wave current is turned into a sine-wave current. Thus, electricity may be supplied to an AC load or the grid. The circuit is protected by isolating the low-voltage side from the high-voltage side. The conversion efficiency is high. The leakage inductance is low. The switch stress is low. The inverter is durable and reliable. Hence, the inverter is suitable for use in a photovoltaic system to increase the total conversion efficiency.
