Optimization Design of Flyback Switching Power Supply Driven by Intelligent Power Module
In order to achieve high efficiency and low cost of intelligent power module(IPM)driving power supply,an isolated multi output flyback switching power supply was designed for IPM driving by utilizing the characteristics of flyback transformers.The voltage stability of the control chip power supply circuit during conversion was optimized.The simulation and experimental results show that the optimized control chip has stable power supply waveform,and the output of the flyback switching power supply reaches stability at 5 ms,with an error of less than 2%and a ripple coefficient of less than 2%.
