| Abstract: | It presents a single-end flyback converter with two outputs based on UC3844.The circuit uses peak current censoring method,together with under-voltage protection.This kind of power supply can be used in IGBT drive,and as the auxiliary power source of high voltage large power supply.It presents the scheme and the practical waveform in the experiment.This power supply has already been used in a full-bridge soft-switching PWM DC/DC converter. |
