| 摘 要： | 本文介绍了电气化铁路的信号电源系统中具有高频链的25Hz逆变电源的设计方法，该方法使得电源的体积和重量大大减小。控制上采用CPLD进行信号时序同步，利用单极性等腰三角波可以方便实现SPWM的双边调制以及逆变器与周波变换器的同步控制。这种控制方法提高了系统的可行性和控制的灵活性。实验结果验证了该电源具有良好的性能。

| Abstract: | A 25Hz inverter power supply with high frequency link is described, which is applied in signal power supply system of the electrization railway. This design makes the size and the weight of the power supply reduced much. By using CPLD in control, signal timing synchronous control is convenient. This control method makes bi modulation of SPWM and synchronous control between the inverter and cycloconverter easier. At the same time, it improved the reliability of the system and the flexibility of the control. The experiment results verify that the power supply has a good performance. |
