【 摘 要 】

This paper analyses capacitor charging characteristics which affects the delay time of DC output of Switch Mode Power Supply(SMPS). By charging experiments of three different capacitors, quantitative analysis of different situations influence and algorithm of the delay time due to ohmic leakage is made. Through theoretical calculation, software simulation and physical circuit experiment, finds a reasonable solution under different charging conditions.
