HYBRID POWER CONVERTING APPARATUS

摘要

PURPOSE: A hybrid power conversion device is provided to reduce power conversion costs by including a common power conversion circuit and a simple selection unit. CONSTITUTION: A conversion unit(10) changes DC or AC power source inputted from an energy source to a DC power source. The conversion unit is operated as the DC-DC voltage booster circuit if an input power source is a DC power source. The conversion unit is operated as the AC-DC full bridge circuit if the input power source is the AC power source. A selection unit(20) interlinks AC or DC power inputted from an energy source to the conversion unit according to a selection signal. A control unit(30) outputs a selection signal for driving the selection unit according to the kind of the energy source.
