  • DC-DC converter with bridge circuit for voltage-free switching, and associated method
    Patent number: 12021457
    Abstract: A bridge circuit including: first and second high-side switches; first and second low-side switches; a transformer having primary and secondary coils; a coil; and a current injection device; wherein the first high-side switch and the first low-side switch are connected at a first bridge terminal in a series circuit to form a first branch; the second high-side switch and the second low-side switch are connected at a second bridge terminal in a series circuit to form a second branch; the first and second branches are connected in a parallel circuit at first and second input terminals; the secondary coil has first and second output terminals; the primary coil and the coil are connected in a series circuit to connect the first bridge terminal to the second bridge terminal; and wherein the current injection device is configured to inject a predetermined current into the coil at a predetermined point in time.
