摘要
本文研究单相逆变器过零点锁相方法,用TI公司的2000系列DSP芯片TMS320F2812,利用了DSP的周期中断和捕获中断来捕获市电电压的过零点,并调节逆变器输出,使其快速跟踪市电电压,完成锁相。最后通过实验验证了该方法的有效性。
This paper studies the single-phase inverter over zero lock method, which uses TI's 2000 series DSP chip TMS320F2812. The main principle is taking advantage of CAP interrupt and period interrupt of DSP to capture zero-crossing point of the electrical network, and adjust the inverter output waveform to fast tracing the electrical network to complete the lock. Finally, the experiments verify the effectiveness of the method.
