| Abstract: | SG3525 is a integrated PWM chip with wide-ranging application. This paper introduces the functions of SG3525 and the drive modular of IGBT, elaborates the design of high-power switching power supply based on SG3525. The half-bridge inverter is used for the power circuit. We get stable output by ,using the methods of feedback and pulse-width modulation. At last ,the result of the experiment has been given. The experiment shows that the power supply is of excellent performance. |
