What is a ZVS resonant converter?

In resonant converters, passive LC circuits are adopted to provide soft switching conditions. In ZVS resonant converters, the switching frequency is increased significantly while the switching, conducting and thermal losses are kept low suitably. Therefore, an ZVS resonant converter is one of the best candidates for a modern power supply [3, 4].

What are the power efficiencies of a ZVS converter?

Experimental results show that the power efficiencies of the converter including SDSR for the light load and the full load are 91.9% and 94.95% at output power Pout = 20 W and Pout = 100 W, respectively. None. ZVS Analyses: The conditions needed to provide ZVS operation are studied in and presented here.

What is a zero voltage switching (ZVS) interleaved high step-up converter?

A zero voltage switching (ZVS) interleaved high step-up converter with coupled inductor and built-in transformer voltage multiplier cell is introduced in this study. A more flexible design is provided by increasing the voltage conversion ratio by utilising the turns ratios of the coupled inductor and built-in transformer.

Which capacitor should be used for ZVS operation?

Here, ZVS operation is not achieved for all switches and a DC-block capacitor should be used in this regard. In [25, 26], the converter core comprised a series-resonant converter and a four-diode full-wave rectifier used at the transformer secondary side, but only two diodes are SR.

Is there a universal ZVS design for a quadratic converter?

The two-stage cascade boost integrated with a coupled-inductor and diode-capacitor voltage multiplier cell has been widely researched due to the advantages of a quadratic voltage gain and low voltage stress for the semiconductor devices. In this paper, the universal ZVS design for a family of quadratic converter is given.

Which technique is used for zero voltage switching (ZVS) performance?

Active clamp technique is utilised for zero voltage switching (ZVS) performance in [31 - 37]. All active switches achieve ZVS operation and both of the switching losses and the imposed voltage on the MOSFETs are significantly decreased. (i) High voltage conversion ratio is obtained.
