Claim 0:
1. A power conversion apparatus, comprising a power conversion circuit, an impedance adjustable circuit comprising a switch and a load circuit, and a control circuit configured to control the switch, wherein the control circuit is connected to both the power conversion circuit and the impedance adjustable circuit, an input end of the power conversion circuit is configured to connect to a power source, and an output end of the power conversion circuit is connected to the impedance adjustable circuit;
the power conversion circuit is configured to adjust output power of the power conversion circuit under the control of the control circuit;
the impedance adjustable circuit is configured to adjust an output impedance of the impedance adjustable circuit under the control of the control circuit;
the control circuit is configured to determine whether or not the power conversion apparatus satisfies a start condition; and
the control unit is configured to, upon a determination that the power conversion apparatus does not satisfy a start condition, control the impedance adjustable circuit to adjust the impedance of the impedance adjustable circuit to a first impedance, and upon a determination that the power conversion apparatus satisfies a start condition, control the impedance adjustable circuit to adjust the impedance of the impedance adjustable circuit to a second impedance, wherein the first impedance is not equal to the second impedance.
