A full-bridge single-stage high power-factor charging circuit has accomplished a lithium battery charger. With no extra design effort required, the presented charger possesses Reflex charging function. Unlike the inherited resistive power dissipation of Reflex charging method, the developed circuit transfers the energy from the battery to an inductive component and return to battery later to fulfill...
This paper proposes an interleaved flyback converter which is remarked with zero-voltage-switched active switches and reduced reverse recovery loss on the rectifying diodes. The configuration is composed of two identical flyback converters and an auxiliary inductor shunted between the diodes. This converter can provide up to 500 W power with highest efficiency as high as 91%.
This paper proposes an interleaved twin-buck converter with zero-voltage-transition (ZVT) for low power applications. The converter comprises two identical buck conversion units employing power MOSFETs as the active power switches with an interleaved inductor. The ZVT is accomplished by resonating the currents between the interleaved inductor and the parasitic capacitances of the power MOSFETs. The...
