Abstract: Today’s switching power supply toward the development of integrated,intelligent,green direction,based on the comparison of the characteristics of current control and voltage control in two modes,it focuses on the working principle and advantages of the current-mode control of switching power supply. Then it introduces the high-frequency single fly back switching regulator power supply with current mode PWM controller UC3842 chip as the core. It describes in detail parameter calculation of the flyback switching power supply. Finally,it gives the power of the test waveform,analysis of the mechanism of the power output ripple.
