Single phase power factor correction ac-dc converters are widely used in industry for ac-dc power conversion from single phase ac mains to an required output dc voltage. In case of high power application these types of converter use an ac-dc boost converter followed by dc-dc converter. These converters has the features of excellent input power factor, continuous input and output currents, and i...

At present scenario, renewable energy sources are needed to meet the energy demand. They also mitigate environment pollution problems. The shortage of electrical energy demand can be meeting with renewable energy resources. A wind turbine (WT) and photovoltaic (PV) solar panels are primary energy sources. Grid connected renewable energy source like wind energy and solar energy are used to conne...

Here an improved three-level integrated ac–dc converter is presented. This converter improving or boosting power factor correction. And also this converter topology is advanced than previous ac-dc converters mainly the converter is operating with two independent controllers. An input controller is used to power factor correction and it regulates the dc bus, and the output controller is used to ...

This research paper proposes a novel bridgeless single-stage isolated converter with power factor correction and load voltage control. The proposed reduces the input diode bridge requirement reduced passive components provides unidirectional flow of to load. design use an electrolytic capacitor, which improves reliability size converter. control method is based on single proportional integral (...
