ABSTRACT:
The unbalance in currents flowing alternately in the two halves of a doubended, push-pull inverter is obviated by means of a parallel resonant network, comprised of an inductor and capacitor, placed in series with the power supply voltage applied to the center tap of the inverter transformer primary winding. The network component values are selected to provide relatively a high impedance of the inverter fundamental operating frequency while providing a low impedance at twice the fundamental operating frequency.
