In this paper, a half-bridge resonant capacitance switching network LLC converter is analyzed and implemented. The half-bridge resonant capacitors switching network is adopted to reduce the input current ripple. The resonant capacitors and the input capacitors are integrated so that the components can be reduced. Two transformers are connected in series on the primary side and in parallel on the secondary...
In this paper, a half-bridge dual LLC converter with symmetrical autotransformer is proposed. The advantages of the proposed converter are that the dual LLC resonant tanks and symmetrical autotransformer can reduce the current stress of components, achieve high efficiency, and increase step-down conversion ratio and high power density. All active switches are turned on at ZVS and rectifier diodes...
This paper proposes an isolated coupled-inductor-integrated dc–dc converter with a nondissipative snubber for solar energy applications. The proposed converter realizes high step-up voltage gain without incurring a high coupled inductor turns ratio by adapting a dual-voltage doubler circuit. In addition, the energy in the coupled inductor leakage inductance can be recycled via a nondissipative snubber...
