摘　　要：本文叙述的调频调压的直流电源与同频斩波电路配合 ,构成一个性能较好的步进电动机的驱动电源。同时对可能出现的故障采取完善的保护措施。其中开关管VMOS和IGBT并联设计 ,有效地提高了效率 ,并防止了功率桥烧管现象的发生。最后对电源的可靠性做了具体的分析。The article describes a well-performance drive power supply of stepmotor which is comprised of frequency-modulated voltage-modulated power supply and synchronous chopper circuit. At the same time, the circuit provides the over-all protection. In circuit, the parallel connection design of MOSFET and IBGT improves the efficiency and prevents it from breaking effectively. Finally, the article also analyzes the dependability of power supply.
