Claim 8:
9. The apparatus according to claim 1, wherein the impedance adjustable circuit comprises a first impedance adjustable circuit and a second impedance adjustable circuit, a first end of the first impedance adjustable circuit is connected in series to a first output end of the power conversion circuit, and the second impedance adjustable circuit is connected in parallel between a second end of the first impedance adjustable circuit and a second output end of the power conversion circuit, or the second impedance adjustable circuit is connected in parallel to the power conversion circuit, and the first impedance adjustable circuit is connected in series to the second impedance adjustable circuit, wherein the first impedance adjustable circuit comprises a first switch and a first load circuit, the first switch is connected in parallel to the first load circuit, the impedance adjustable circuit comprises a second switch and a second load circuit, the second switch is connected in series to the second load circuit, and the first switch and the second switch are further connected to the control circuit;
upon determination that the power conversion apparatus does not satisfy the start condition, the control circuit is configured to control the first switch to be in a first state, and is configured to control the second switch to be in a first state or a second state, wherein the second state is a state different from the first state; or
upon determination that the power conversion apparatus satisfies the start condition, the control circuit is configured to control at least one of the first switch and the second switch to be in a state that is different from a state corresponding to the at least one switch when the power conversion apparatus does not satisfy the start condition.
