摘要
介绍了一种应用高频链逆变技术设计的频率、相位和幅值精准的航空陀螺驱动精密逆变电源。在周波变换器的控制、SPWM触发脉冲的生成以及保护电路等部分使用配置灵活的CPLD,并给出了软硬件上的实现。实验结果表明,该电源在实际应用中,达到或超过了传统的交流驱动的指标,并在小型化、提高功率密度和可靠性方面,取得了很好的效果。
A new design of a high accuracy inverter power is achieved, with the accurate and constant frequency, phrase and amplitude output, by including the high frequency link. Using the flexible device CPLD, in the control of cyclone converter, generation of SPWM wave and electrical protection, brings the system with small volume and weight, high reliability and power density. The realizations of the software and hardware are introduced in details. The results of experiment verify its satisfying performance.
