Abstract
A current-fed full-bridge DC-DC converter includes a current source circuit including a direct-current voltage source circuit and a reactor connected to the direct-current voltage source circuit in series, an inverter circuit including switching elements, input terminals and output terminals, wherein outputs of the current source circuit are connected to the input terminals, a transformer having a primary coil that is connected to the output terminals and a secondary coil and a rectifier circuit which is connected to the secondary coil and through which the current-fed full-bridge DC-DC converter generates direct-current output. The current-fed full-bridge DC-DC converter further includes a capacitor connected to the output terminal and the primary coil in series and a controller controlling on/off operations of the switching elements so that a current can flow from the current source circuit through the primary coil and the capacitor in stopping of the current-fed full-bridge DC-DC converter.
