| 摘 要： | 恒频恒压(CVCF)逆变电源的输出电压波形质量是衡量其性能的重要指标之一。文章采用一种重复控制和双闭环控制相结合的电压波形控制策略,以重复控制器提高逆变电源输出电压的稳态精度,减小总谐波畸变率;以双闭环控制器达到较快的动态响应速度。该方案在一台采用TMS320F240DSP控制芯片的50Hz三相PWM逆变器上得到验证。

| Abstract: | The quality of output voltage waveform of CVCF inverters is one of the most important aspects for evaluation of inverters' performance.A kind of waveform control scheme based on repetitive control and double-loop control is adopted in this paper.The repetitive controller improves the steady-state performance and restrain the harmonic component disturbance of output waveform,while the double-loop controller improves the dynamic performance.This scheme is proved on a 50 Hz three-phase PWM inverter with a TMS320F240 DSP controller. |
