摘　　要：设计了一种基于TOP246Y芯片的单端反激式多路输出开关电源,电源提供八路输出,为电机伺服系统中的功率板和控制板提供可靠的工作电压.实验表明,电源能够在输入电压波动较大的情况下提供稳定的直流输出,达到设计指标要求.The paper designed a single-ended flyback multi-output switching mode power supply based on TOP246Y chip,which has eight outputs and provides a reliable voltage for the motor servo system in the power board and control board. This paper mainly introduced the high-frequency transformer and chip peripheral circuit design. According to the requirements of the design, the circuit diagram, the calculation step of main parameter of transformer as well as the main 5 V output t voltage waveform were presentecl. Experiments show that the power can provide a stable DC output to meet the design target requirements in the case of input voltage fluctuations.
