Abstract :
One cycle control method to control the DC-link voltage is proposed for three phase quasi Z-source inverter. The diode voltage is chosen as a switched variable. A sine-triangle PWM method is used as a modulation method The shoot-through is inserted when triangular carrier crosses positive and negative reference line respectively. The total shoot through time will be decided by one cycle controller. One cycle controller offers fast dynamic response, input voltage disturbance rejection. Simulation results are presented to support the proposed method.
