ABSTRACT:
A switching circuit that includes two parallel connected switching transistors. A primary winding of a transformer is connected across the drain electrodes of each of the switching transistors and a secondary winding of the transition transformer is connected to the gate electrodes of the transistor. A capacitor is connected in series with the primary winding to isolate the primary winding from the switching circuit when in a steady state operation. The secondary winding shorts the commonly connected gate electrodes in the steady state condition. The differential in voltage between the drain electrodes is used to activate the primary winding of the transformer which induces a correction voltage in the secondary winding to cause the transistors to operate at the same rate.
