Abstract

A power conversion apparatus and method are provided. The apparatus includes a main battery and a power converter configured to execute a high power conversion mode that generates a high power and a low power conversion mode that generates a low power using an input power from the main battery. Additionally, an auxiliary battery is configured to receive and charge the low power and an inverter is configured to convert the high power to a driving power for driving a motor.

Description

technical field [0001] The present invention relates to power conversion devices and methods, and more particularly, to power conversion devices and methods that reduce size and improve efficiency in eco-friendly vehicles. Background technique [0002] A hybrid vehicle among eco-friendly vehicles refers to a vehicle using two power sources. For example, a hybrid vehicle refers to a vehicle that has an electric motor that runs on electricity and an engine that runs on gasoline combustion. [0003] Therefore, a general hybrid vehicle includes two or more controllers to operate the two power sources respectively. Therefore, although the motor and the engine differ from system to system, the vehicle may be composed of two power sources of the motor and the engine, and may include: an engine control unit (hereinafter referred to as ECU (engine control unit)) configured to operate the engine; A motor control unit (hereinafter referred to as MCU (motor control unit)) configured t...
