| Abstract: | This paper puts forward a switching mode power supply scheme that applies to medical equipment. The scheme is based on the high performance PWM integrated chip of electric current mode. The design adopts medical equipment for AC To DC and gets 90-264V alternating current power supply and 12V direct current output. It can well satisfy the power supply demand for medical equipment because it has some important advantages, such as quick response, good EMC, excellent stability and precise voltage output. The paper provides the thought about designing the switch power as well as analyses and discusses on technological details. |
