[0018] image 3 , Figure 4 , Figure 5 , Image 6 It is the switching state of the inverter example implemented using the inverter topology of the present invention during operation. image 3 with Figure 4 Is when the inverter outputs a positive half wave of AC, Figure 5 with Image 6 This is when the inverter outputs a negative half wave of AC. When the inverter outputs a positive AC half-wave, the commutation switches S2 and S3 are kept in the on state; the commutation switches S1 and S4 are kept in the off state, and their blocking voltage is Vout. When the inverter outputs a negative half-wave of AC, the reversing switches S1 and S4 remain in the on state; the reversing switches S2 and S3 are kept in the off state, and their blocking voltage is Vout. Chopper switches S5 and S6 are switched at high frequency at the same time, image 3 with Figure 5 Is the situation when they are opened, Figure 4 with Image 6 This is the situation when they are off. When S5 and S6 ar...
