摘要： A DC to DC converter includes: first and second switching elements connected in series at a first connection point between a first input/output terminal and a first ground terminal; third and fourth switching elements connected in series at a second connection point between the first input/output terminal and the first ground terminal; a resonant capacitor and a resonant inductor connected in series between the first and second connection points; fifth and sixth switching elements connected in series at a third connection point between a second input/output terminal and a second ground terminal; seventh and eighth switching elements connected in series at a fourth connection point between the second input/output terminal and the second ground terminal; a transformer; and a control circuit. The transformer has a primary winding connected in series to the resonant capacitor and the resonant inductor between the first and second connection points, and a secondary winding connected in series between the third and fourth connection points. The control circuit is operable to adjust the pulse waveforms for switching the fifth to eighth switching elements when voltage at the second input/output terminal is stepped down and output from the first input/output terminal.

摘要： A charge-discharge device includes a DC-DC converter configured to be electrically connected to a secondary battery, an inverter electrically connected to the DC-DC converter, a main charging terminal electrically connected to the inverter, a voltage detector for detecting a voltage of the main charging terminal, and a control circuit electrically connected to the DC-DC converter, the inverter, and the voltage detector. While the secondary battery is charged with a voltage input to the main charging terminal, when the voltage detected by the voltage detector is a DC voltage, the control circuit switches, according to the voltage, between an operation to cause the inverter to supply the voltage substantially intactly to the DC-DC converter, and cause the DC-DC converter to charge the secondary battery and an operation to cause the inverter to function as a DC voltage conversion circuit that converts the voltage and supplies the converted voltage to the DC-DC converter, and cause the DC-DC converter to charge the secondary battery. This charge-discharge device enables secondary batteries to interchange electric power with each other via a simple, light-weight outlet cable.
