Problems solved by technology

[0003] Traditional converters use diodes as components of the electronic switches in the secondary side circuit. Since the diodes will generate a considerable power loss, the conversion efficiency of the converter cannot be improved. Therefore, the electronic switches in the secondary side circuit can be improved to avoid a large amount of power loss. Become the technology development target of the converter

The first endpoint of the secondary winding thereof isin tandem connection with the first electronic switch and the first energy storage assembly, the second endpoint is in tandem connection with the second electronic switch and the second energy storage assembly, the first endpoint of the load end is in connection with the first and the second energy storage assemblies at the same time, and the second endpoint is in connection with the central endpoint of the secondary winding.

Description

technical field [0001] The invention relates to a voltage converter, especially a synchronous half-wave rectification converter capable of achieving zero-voltage conversion and low power loss. Background technique [0002] Traditionally, the half-bridge converter is a converter that uses two power switches and performs forward power conversion, which can be applied to a smaller transformer. The high-efficiency power conversion power supply pursues its development goal, and the LLC resonant circuit can reduce Power switching loss, improving power conversion efficiency and reducing energy loss, is a product developed by the current related power supply industry. [0003] Traditional converters use diodes as components of the electronic switches in the secondary side circuit. Since the diodes will generate a considerable power loss, the conversion efficiency of the converter cannot be improved. Therefore, the electronic switches in the secondary side circuit can be improved to ...
