Patent ID: 8564973

Claim:
An inverter topology circuit, comprising: a direct current source, an alternating current source, a first bridge arm, a first inductor, and a second inductor, wherein the first bridge arm is connected in parallel to two poles of the direct current source, one ends of the first and second inductors are connected to connection points of two branches of the first bridge arm, respectively, and the other ends of the first and second inductors are connected to two poles of the alternating current source, respectively; a fifth switch tube, a sixth switch tube, a fifth diode, a sixth diode, and a first capacitor; wherein: the fifth switch tube is connected in parallel to the fifth diode, and the sixth switch tube is connected in parallel to the sixth diode; same poles of the fifth and sixth diodes are connected to one pole of the direct current source together, the other pole of the fifth diode is connected to a connection point between the second inductor and the alternating current source, and the other pole of the sixth diode is connected to a connection point between the first inductor and the alternating current source; and the first capacitor is connected in parallel to two poles of the alternating current source.
