Conversion device for automobile

A conversion device for an automobile, comprising:

• a plurality of input ports including a first, second, and third input port functioning to receive power input;
• a conversion circuit comprising an input conversion module, a DC/DC converter, a DC/AC inversion converter, a bi-directional DC/DC converter, and a DC bus having an input side and an output side, the input side of the DC bus being connected to the input conversion module, the output side of the DC bus being connected to the DC/DC converter, the DC/AC inversion converter, and the bi-directional DC/DC converter for converting the power input from each of the input ports, the input conversion module comprising a bi-directional AC/DC converter and a DC/DC converter;
• a power flow sensor connected between each of the input ports and the input conversion module of the input side to sense and feed power flow of the power input from each of the input ports to the conversion circuit for carrying out power conversion, the power flow sensor senses the power flow from each input port to facilitate selection of one or more of the input ports to receive the power input;
• a plurality of output ports including a first, second, and third output port respectively connected to the converters of the output side for output power, the input ports commonly connected to the power flow sensor, the first input port being connected via the power flow sensor to the bi-directional AC/DC converter of the input side, both the second and third input ports being connected via the power flow sensor to the DC/DC converter of the input side, and the output ports respectively connected to the converters of the output side;
• an input selector connected to each of the input ports and the power flow sensor, whereby the input selector bases on input power flow detected by the power flow sensor to select one of the input ports to realize the input power;
• a first timer connected to the input selector to effect time-measuring for power input, whereby the time when each input port inputs power is controlled on the basis of the first timer;
• an output selector connected to each of the output ports and the converters of the output side commonly connected to the output selector for selection of one or more than one of the output ports to supply the output power;
• and
• a second timer connected to the output selector to effect time-measuring for power output, whereby the time when each output port outputs power is controlled on the basis of the second timer;
• wherein the power input at the input ports are converted by the conversion circuit and supplied through the output ports and wherein the power flow sensor functions to detect the power flow of the input power at the input ports.
