Claim 11:
12. A method for controlling an output impedance of a power conversion apparatus comprising a power conversion circuit, an impedance adjustable circuit comprising a switch and a load circuit, and a control circuit, the control circuit connected to both the power conversion circuit and the impedance adjustable circuit, and an output end of the power conversion circuit being connected to the impedance adjustable circuit, the method comprising steps of:
determining whether or not the power conversion apparatus satisfies a start condition;
adjusting the output impedance of the power conversion apparatus to a first impedance upon determination that the power conversion apparatus does not satisfy the start condition; or
adjusting the output impedance of the power conversion apparatus to a second impedance upon determination that the power conversion apparatus satisfies the start condition, wherein the first impedance is not equal to the second impedance.
