摘要： An inverter system has first and second resonating current sources (50-63, 70-83) which are resonant at the same frequency. The currents of the two sources are combined. At lower power levels, the currents are substantially out of phase and the frequency is adjusted. At intermediate power levels, the phases of the currents are adjusted and the frequency is fixed. At high power levels, the currents are substantially in phase and the frequency is adjusted.
