| Abstract: | Based on analyzing the defects of traditional topology used in the design of high voltage auxiliary power, a new kind of digital to analog control auxiliary power supply design scheme for high voltage converters was proposed. The principle of the proposed design scheme was analyzed, and a more comprehensive study was made to estimate the parameters in the design of start-up circuits for MCU control auxiliary power supply, PWM control circuits, flyback main circuits and transformers. Finally, a demo board was designed with this topology. Both simulation and test results showed that the circuit met the design target. |
