一种低损耗整流电路
摘要：
本实用新型公开了一种低损耗整流电路，其包括第一、第二、第三、第四二极管；此外其还包括：与所述四个二极管对应并联的四个MOSFET；逻辑控制模块，其包括信号分压器、比较电路、反向器和三态门，所述逻辑控制模块控制各MOSFET的导通和截断，以使各MOSFET在导通的状态下替代与其对应并联的二极管作为整流变换信号的通道。本实用新型公开的低损耗整流电路，其使得整流电路具有极低的整流压降，从而能有效减少整流电路的损耗。
摘要（英）：

The utility model discloses a low-loss rectification circuit. The low-loss rectification circuit comprises a first diode, a second diode, a third diode and a fourth diode. The low-loss rectification circuit also comprises four MOSFETs in corresponding parallel connection with the four diodes, and a logic control module. The logic control module comprises a signal voltage divider, a comparison circuit, a reverser and a three-state gate. The logic control module controls on and off of each MOSFET, thus each MOSFET replaces the diode in corresponding parallel connection as a channel of a rectification conversion signal in an on state. The low-loss rectification circuit has an extremely low rectification voltage drop and therefore loss of the rectification circuit can be lowered effectively.
