description A DC-DC converter is operated in a boost mode by operating a plurality of low-voltage side switches with a first fixed duty cycle (greater than 0.5), with cutting off a plurality of the first high-voltage side switches and a plurality of the second high-voltage side switches, with conducting a plurality of the first diodes of the first high-voltage side switches and a plurality of the second diodes of the second high-voltage side switches, and with alternatively conducting and cutting off a bidirectional switch. In a buck mode, the low-voltage side switches are cut off and a plurality of diodes of the low-voltage side switches are conducted. Furthermore, the first high-voltage side switches are complemented and are operated with a second fixed duty cycle (less than 0.5) while the second high-voltage side switches are conducted and cut off alternatively and the bidirectional switch is switched on and off.
