摘要
针对传统脉冲宽度调制(SVPWM)的逆变电源,效率低,可靠性差等缺点,采用空间电压脉宽调制(SVPWM)技术改善逆变电源的输出波形质量,并在Matlab/Simulink环境下对SVPWM控制的逆变器系统进行了仿真,给出了相应的仿真结果。为了实现全数字化控制,提出了用DSP生成SVPWM的方法。在分析TMS320LF2407数字信号处理器芯片特点的基础上,给出系统实现的软硬件结构。该系统电路简单、可靠性高。
Aiming at the disadvantages of SVPWM inverter power source using Traditional pulse width modulation those efficiency is not high and the reliability is bad, the paper introduces the Space Vector PWM (SVPWM) in order to improve the output wave quality of the inverter power supply. The Simulation models of SVPWM inverter are built up by Matlab/Simulink and the simulation results are shown. To accomplish full digital control, SVPWM wave is produced by using DSP. On the base of analyzing the characteristic of T...
