摘要
针对 3 0 k W开关磁阻电机控制系统的需要 ,本文设计了 Flyback辅助开关稳压电源。此电源给系统控制板以及IGBT驱动电路供电 ,并保证电源电压稳定 ,纹波不大于 3 % ,控制板电源与驱动电路电源以及 IGBT驱动电路电源之间相互隔离。本文重点论述了开关电源的电路设计及高频变压器的设计 ,并给出实际纹波波形。本文设计的开关电源经现场检验 ,性能良好。本开关电源经改动后也适用与其他使用 IGBT器件的电力电子装置。
The paper designed a Flyback switching power supply for switched reluctance motor control system. The power supply the control board and the IGBT drive circuits, the control board power supply and IGBT drive circuit power supply is insulated. The paper emphasized on switching power circuit design and highfrequency transformer design. The switching power supply is used in SRM control system and run well. After mended, the switching power supply will adapt to power electronic system with IGBT.
