Patent ID: 8675375

Claim:
A DC/DC converter for use with a DC input signal and a load, said DC/DC converter comprising: a control signal generator operable to generate a first primary side control signal, a second primary side control signal, a first secondary side control signal, a second secondary side control signal and a third secondary side control signal; a primary side winding; a first primary side switch operable to pass, based on the first primary side control signal, the DC input signal through said primary side winding in a positive direction to generate a first magnetic field; a second primary side switch operable to pass, based on the second primary side control signal, the DC input signal through said primary side winding in a negative direction to generate a second magnetic field; a secondary side winding coupled with said primary side winding, said secondary side winding being operable to generate a first current in the positive direction based on the first magnetic field and to generate a second current in the negative direction based on the second magnetic field; a first secondary side switch operable to pass the first current to the load based on the first secondary side control signal; a second secondary side switch operable to pass the second current to the load based on the second secondary side control signal; a voltage generating portion operable to receive the first current and the second current and to generate a surge voltage based on the third secondary side control signal; a threshold voltage providing portion operable to generate a threshold voltage; and a feedback signal generator operable to generate a feedback signal based on the surge voltage and the threshold voltage, wherein said control signal generator is further operable to modify one of the first primary side control signal, the second primary side control signal, the first secondary side control signal, the second secondary side control signal and the third secondary side control signal based on the feedback signal.
