Abstract: Based on the single-ended flyback circuit, this paper designed an auxiliary power supply of control system with alternating current input voltage from 85 to 265 and 24 voltage of direct current output and expounded the transformer design process of single-ended flyback converter, carrying out the small signal analysis of feedback loops and compensation network optimization. The prototype was produced and comprehensive experiments were conducted. The experimental results show that the power supply is stable and has good dynamic performance, whose overall efficiency reaches 89.4%, which can meet the auxiliary power supply requirements for the multi-axis motion platform of linear motor. 
Key words: linear motor; auxiliary power supply; single-ended flyback; feedback loop
