摘要
将电压空间矢量脉宽调制技术应用于三相逆变器控制系统中,详细介绍了简单SVPWM调制算法,设计了以TMS320F28335 DSP为处理器,以IGBT为功率器件的三相逆变电源数字控制系统。结果表明:该系统实现简单,具有较高的功率因数,能保证较好的供电质量。
The paper introduced the control scheme of voltage space-vector pulse modulation for the three-phase inverter. The simple SVPWM algorithm is derived in detail. The digital control system with TMS320F2812 DSP as processor and IGBT as power device is designed. The experimental waveform shows that the control system is easy to realize,the power factor is nearly unity and would ensure the good power supply quality.
