This study presents a new DC/DC converter for high input voltage and high load current applications. To adopt low voltage rating power devices in high voltage applications, two split capacitors with four active switches are used in the primary side to reduce the voltage stress of power switches at Vin/2. Two flying capacitances are used to automatically balance two split capacitor voltages in every...
This paper addresses the control of a Dual Active Bridge (DAB) dc/dc converter. Closed-loop control of the output voltage is achieved by a novel nonlinear technique that separates the control algorithm into a linearization stage and a linear control law. The resulting DAB is capable of bidirectional power flow, and the transformer isolation makes it suitable for a wide variety of applications. The...
This paper proposes a new bridgeless single-stage half-bridge ac-dc converter. The proposed converter integrates the operation of the bridgeless power factor correction (PFC) boost rectifier and the asymmetrical pulse-width modulation (APWM) half-bridge dc-dc converter. The proposed converter provides high power factor and direct power conversion from the line voltage to an isolated dc output voltage...
