      Design of Three Phase Variable Frequency and Amplitude of Inverter Power Supply Based on SVPWM

      摘要:
      从模拟电源存在的缺陷出发,通过对空间矢量脉宽调制算法的分析,研究了一种基于SVPWM技术的三相变频变幅逆变电源.在此基础上,还提出了逆变电源闭环控制的PI控制算法,为了提高系统响应速度,设计采用具有强大数字信号处理能力的DSP作为硬件平台,最后完成了各项相关的验证实验,结果表明:系统实现了步进为1 V、范围在40 V以内的调压输出和步进为2 Hz、范围在50 Hz~1 kHz的调频输出,系统的负载调整率小,性能优良,具有良好的应用前景.
      Abstract:
      In this paper , based on the analysis of the space vector pulse width modulation algorithm , a three phase inverter power supply based on SVPWM technology was studied from the flaws of analog power supply .On this basis, the control algo-rithm of PI inverter closed-loop control was proposed , in order to improve the system response speed , with powerful digital signal processing ability of the DSP as the hardware platform , the related experiments were finished .The results show that the system can complete the step for 1 V, and output range within 40 V regulator and the step is 2 Hz in the range of 50 Hz~1 kHz frequen-cy output.The system load adjustment rate is small , it has excellent performance and a good application prospect.
