Classification: CPC H  G  Y | IPC H

Claim 17:
18. The method according to claim 12, wherein the power conversion apparatus comprises a buck-boost circuit;
the adjusting the output impedance of the power conversion apparatus to a first impedance upon determination that the power conversion apparatus does not satisfy a start condition comprises:
controlling, upon determination that the power conversion apparatus does not satisfy the start condition, a status of a first-type switch to change according to a first law, wherein the first-type switch is a switch that can change the output impedance of the power conversion apparatus and that is in the buck-boost circuit, and the first law is determined based on the first impedance; and
the adjusting the output impedance of the power conversion apparatus to a second impedance upon determination that the power conversion apparatus satisfies a start condition comprises:
controlling, upon determination that the power conversion apparatus satisfies the start condition, a status of a first-type switch to change according to a second law, wherein the second change law is determined based on the second impedance.
