摘要
The voltage modulation factor of the magnetic flux control pulse-width modulation (PWM) method is discussed. The modulation factor is derived from a theoretical study on the flux locus produced from inverter output voltage for the first time. The derivation is based on the fact that the fundamental component of the inverter output voltage is proportional to the radius of the flux locus. As the theoretical result, it was made clear that the voltage modulation factor is expressed by a content of a zero vector in one cycle of the selected PWM pattern of the space vector expression. The modulation factor of the magnetic flux control PWM method is calculated. The above modulation factor can be varied from zero to 12/pi-2. The output voltage of the magnetic flux control PWM method can be controlled by the proposed modulation factor from zero up to the overmodulation linearly. The simulation and experimental results are also shown.
