Abstract The power supply adopts TOP244Y chip as ,the main control core, and the feedback circuitcomposed of TL431 and PC817 realizes 4 isolated outputs with a power of 24 W, which can provide an efficientand reliable power supply solution for PMSM system. Through theoretical calculation, simulation and experimental verification, the power supply has achieved good results in the key indicators such as voltage output accuracy, ripple, load regulation and efficiency, and meets the design requirements of PMSM system.
