In this paper, the authors deal with reducing switching loss, reducing voltage and current stresses and reducing conduction loss due to circulation current. An isolated bidirectional full-bridge DC-DC converter with high conversion ratio, high output power and soft start-up capability is proposed. The use of a capacitor, a diode and a flyback converter can clamp the voltage spike caused by the current difference between the current-fed inductor and leakage inductance of the isolation transformer and can reduce the current flowing through the active switches at the current-fed side.
