Popis: The paper studies a switching loss minimized PWM method for flying capacitor multilevel inverter. Using the method, each phase of the flying capacitor multilevel inverter can have the 120° no switching zone in one period; according to power factor angle, 120° no switching zone can be adjusted to be farthest located in the centre of the peak value region of the load current, the switching loss can be greatly reduced and the efficiency of the system can be greatly improved. the simulation and experimental results show that switching loss of 33%is reduced.
