摘　　要：空间矢量脉冲调制技术(SVPWM)通过对逆变器上的六个开关器件的开关组合,能够控制输出电压的运动轨迹为圆形,此时逆变器输出电压的最大值为圆的半径。为了扩展逆变器最大电压的输出范围,提出了一种SVPWM过调制算法。仿真结果表明:过调制技术的引入,能够有效提高逆变器的最大输出电压。The space vector pulse modulation technology(SVPWM)can control the trajectory of the output voltage to be a circle through the switch combination of the six switching devices on the inverter.At this time,the maximum value of the inverter output voltage is the radius of the circle.In order to extend the maximum voltage output range of the inverter,a SVPWM over-modulation algorithm is proposed.The simulation results show that the introduction of over-modulation technology can effectively increase the maximum output voltage of the inverter.
