PROBLEM TO BE SOLVED: To provide a full bridge system bidirectional insulation DC/DC converter capable of transmitting power from a primary power supply to a secondary power supply at the time of powering, and capable of transmitting power from the secondary power supply to the primary power supply at the time of regeneration, without switching the control method of each switching element at the time of powering and regeneration.SOLUTION: A full bridge system bidirectional insulation DC/DC converter 1 includes switching elements Q1-Q4 in full bridge connection on the primary of a transformer T1, switching elements Q5-Q8 in full bridge connection on the secondary of the transformer T1, and a control unit 2. The control unit 2 is configured to control on/off state of the switching elements Q1, Q2, Q5, Q7 depending on a drive signal DR1 repeating active state and non-active state at a predetermined cycle, and to control on/off state of the switching elements Q3, Q4, Q6, Q8 depending on the active state of a drive signal DR2 obtained by shifting the phase of the drive signal DR1.SELECTED DRAWING: Figure 1 |
