Abstract
A protection circuit protects transistors in a DC-DC conversion circuit from over voltages. The transistors in the conversion circuit include first and second transistors. Converted energy is driven across a transformer by an H-bridge circuit. With a first configuration of the H-bridge circuit, a third transistor is turned on to discharge an inductor that was previously charged. The inductor is coupled to the third transistor. The discharging of the inductor boosts an output current of the conversion circuit. A capacitor is charged through a diode. The capacitor and diode are disposed in the protection circuit. The diode is coupled to the first transistor and the charging of the capacitor is effective to limit voltage across the first transistor.
