ABSTRACT:
A system controls a transformer having a primary coil. A pulse is applied to an inverter associated with the primary coil, whereby a leading edge of the pulse creates in the primary coil a tank circuit current of an initial polarity in a tank circuit inherent to the transformer. The tank circuit is seen from an effective inductance in series with the primary coil, the effective inductance including a leakage inductance of the primary coil, and an effective capacitance in parallel with the primary coil, the effective capacitance including a parasitic capacitance of the transformer. A trailing edge of the pulse occurs when the tank circuit current is different from the initial polarity.
