1. A power conversion apparatus comprising:
- an output circuit unit configured to generate output power;
a first controller configured to acquire a value representing the output power, to compare the acquired value of the output power with a reference value, and to perform a switching control for generating boosted power;
a first-stage input unit configured to receive battery power and to generate boosted power according to the switching control;
a second-stage input unit configured to convert the boosted power or the battery power into another power; and
a conversion unit configured to perform a conversion operation on the other power for the sake of the output power.

11. A method of operating a power conversion apparatus of a vehicle, comprising:
-
acquiring a value representing output power which is supplied to an electric load in the vehicle; comparing the acquired value of the output power with a reference value to determine if battery power from a battery is to be boosted; when determined that the battery power is to be boosted, supplying the battery power to a first-stage input unit; generating, by the first-stage input unit, boosted power by performing a switching control to boost the battery power; supplying the boosted power to a second-stage input unit; converting, by the second-stage input unit, the boosted power into converted power; and converting, by an output circuit unit, the converted power into the output power, when determined that the battery power is not to be boosted, supplying the battery power to the second-stage input unit; converting, by the second-stage input unit, the battery power into converted power; and converting, by an output circuit unit, the converted power to the output power. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
