Abstract

A conversion device is provided for an automobile, including a conversion circuit, input port(s), output port(s), and a power flow sensor. The input port function to receive a power input. The conversion circuit includes a DC bus and a plurality of converters. An input side of the DC bus is connected to an input conversion module, and an output side of the DC bus is connected to a DC/DC converter, a DC/AC inversion converter, and a bi-directional DC/DC converter for converting the power input from the input port. The power flow sensor is connected between the input port and the input conversion module of the input side to sense and feed power flow of the power input from the input port to the conversion circuit for carrying out power conversion. The output port is connected to the converters of the output side for output of power. As such, the power input at the input port is converted by the conversion circuit and supplied through the output port and the power flow sensor detects the power flow of the input power at the input port to various power sources to continuously supply power to the automobile thereby providing practicability and convenience of ensuring continuous supply of power and substantially enhancing the cruising distance of the automobile.
