摘要
根据开绕组电机伺服驱动电路中需要多路电源供电的情况,设计了一款基于TOP247Y的单端反激式开关电源。根据开绕组电机的拓扑结构特点,着重分析高频变压器的设计,计算开关电源的参数,最后介绍开关电源的部分外围电路设计,后续采用直流稳压模块对开绕组电机拓扑逆变器各桥臂单独供电。通过实验证明所设计的开关电源适用于开绕组电机伺服驱动。
According to the needs of multi-channel power supply in the servo drive circuit of open winding motor,a single-terminal fly-back switching power supply based on TOP247Y was designed.According to the characteristics of the topology of the open winding motor,the design of the high-frequency transformer was analyzed emphatically,and the parameters of the switching power supply were calculated.Finally,the design of some peripheral circuits of the switching power supply was introduced.Subsequently,DC voltage stabilization modules were used to supply power to each bridge arm of open winding motor topology inverter separately.The experimental results show that the designed switching power supply is suitable for servo drive of open winding motor.
