Abstract
An inverter system having two resonating current sources which are resonant at the same frequency. The currents of the two sources are combined. At low power levels, the currents are substantially out of phase and the frequency is adjusted. At intermediate power levels, the currents are adjusted in phase and the frequency is fixed. At high power levels, the currents are substantially in phase and the frequency is adjusted.
