Beschreibung
Zusammenfassung:	The invention provides a circuit control device and method, and belongs to the technical field of power supplies. The device comprises a PFC circuit, wherein the PFC circuit is arranged on the primary side of a high-frequency transformer, a switch tube in the PFC circuit is used for controlling the voltage direction and the voltage magnitude of a primary inductor of the high-frequency transformer, and the PFC circuit has bus voltage and PFC current; an output circuit arranged on the secondary side of the high-frequency transformer, and the output end of the output circuit has output voltage; and a control circuit connected with the output circuit and the PFC circuit, wherein the control circuit is used for controlling the switch-on and switch-off of the switch tube through the output voltage, the bus voltage and the PFC current. The stability of the output voltage is improved. 本申请提供了一种电路控制装置和方法，属于电源技术领域。所述装置包括：PFC电路，所述PFC电路设于高频电压器的原边侧，所述PFC电路中的开关管用于控制所述高频电压器的原边电感的电压方向和电压大小，所述PFC电路中具有母线电压和PFC电流；输出电路，所述输出电路设于所述
