According to the technical requirements of general frequency converter for control power supply,a multi-output single-end flyback switch control power supply suitable for general frequency conversion device is designed to provide control and drive power for the frequency converter. The principle design of the control power supply,the calculation of the main device parameters,and the experimental verification of the output voltage ripple are introduced in detail. The final results show that the designed control power supply meets the requirements of the output voltage and ripple of the general frequency converter.
