The design of a new multi-output switching power supply based on UC3844 is proposed in this paper. The design of transformer, leakage inductance elimination circuit, start circuit and voltage and current feedback circuit are introduced in detail. Experiment results show that the power supply has good performance such as high voltage stability, low output voltage ripple, good load adjustment rate and so on. It can be used for motor control as a power module and has a better practical value.
