Beschreibung
Zusammenfassung:	The invention provides a current sharing circuit and a power supply, the current sharing circuit is arranged at the input end of a current detection amplifier of a current sharing controller and is used for generating a bias voltage, and the output voltage of the current detection amplifier is higher than a preset driving voltage during no-load or light-load, so that error voltage caused by misoperation of a current control loop is avoided, and the reliability of the current sharing circuit is improved. And the precision of the output voltage of the current sharing controller is ensured. 本申请提供一种均流电路及电源，设置于均流控制器的电流检测放大器的输入端，用于产生偏置电压，当空载或轻载时，使得所述电流检测放大器的输出电压高于预定驱动电压，从而避免电流控制环路误操作，导致产生误差电压，保证均流控制器输出电压的精度。
