In the electronic circuit and automatic control device, need DC regulated power supply voltage is very stable. In the DC power supply occasions, is widely used in DC regulated power supply. This topic is very close to our daily life, and to the professional knowledge of power electronic devices, rectification, filtering technology, inverter technology and control technology for us, but we need to skillfully use the drawing software draw circuit diagrams, and can use the simulation software is simple, the simulation effect. This can make us more familiar with these knowledge. We are in the process of the design according to the power supply output voltage and the maximum output current to determine the types and forms of circuits integrated voltage regulator. The input voltage of the regulator to determine power transformer two winding voltage effective value; based on the maximum output current stabilized power supply is determined through a power transformer two times two times winding current and power transformer power transformer; according to the power found efficiency, so as to determine the power of the original side of the power transformer. Then according to choose the parame
