Firstly , three - phase static inverter under the space vector pulse width modulation ( svpwm ) is analyzed . then instantaneous control for three - phase static inverter is implemented in the synchronization frame through dq transform to get the information about amplitude and phase of output voltage 本文在对空间矢量脉宽调制( svpwm )方式下三相静止变流器分析的基础上,通过dq坐标变换提取输出电压幅值与相位的信息,实现在同步坐标下对三相静止变流器的瞬时值控制。
