ABSTRACT:
An inverter system having a plurality of resonating current supplying stages connected in parallel, all resonant at the same frequency. The rate at which the stages operate is controlled by a feedback circuit responsive to the load output. The rate is maintained above the audible range for all but small total current values. Should the rate tend to vary outside a predetermined range, a different combination of stages is switched in. The stages supply currents which are binary weighted.
