WebOvermodulation The modulation index, which measures the ability of the power converter to output a given voltage, is defined as m = V M V C, where m is the modulation index. Vm is the peak value of the modulation wave. Vc is the peak value of the triangle carrier wave. For three-phase SPWM, V p e a k = m v d c 2, where WebDPWM and overmodulation to reduce device conducting periods, based on two-level SVPWM control technology [21]. As a result, the device power losses are reduced e ectively. Moreover, the overmodulation segment control method can also reduce the harmonic distortion of the output voltage and improve the DC-link voltage utilization.
