摘要

本文提出了一种电隔离全桥整流器，利用自适应零电流检测(ZCD)方法来消除二极管下降和反向电流。整流器的设计和仿真采用0.18µD的BCD工艺，有源面积为0.64 mm2。仿真结果表明，自适应零电流检测能显著降低反向电流，提高传输效率。当负载为75mA时，该电路的传输效率为92%。比二极管全桥整流器高12.3%。

A Galvanic Isolated Full Bridge Rectifier with Adaptive Zero Current Control

This paper proposes a galvanic isolated full-bridge rectifier that utilizes an adaptive zero current detection (ZCD) method to eliminate the diode drop and reverse current. The rectifier is designed and simulated using a 0.18µD BCD process with an active area of 0.64 mm2. The simulation results demonstrate that the adaptive zero current detection can significantly reduce reverse current and improve transmission efficiency. With a load of 75mA, the circuit achieves a transmission efficiency of 92%. which is 12.3% higher than that of a diode full-bridge rectifier.
