System for controlling variable frequency self-excited resonant inverter power transistors

摘要

System for controlling variable frequency self-excited resonant inverter power transistors by means of at least one transformer with a plurality of primary and secondary windings energised by at least two transistors. The transformer or transformers that is/are used have a saturated core. A continuous current is passed through at least one of the windings, with which current a core is established prior to saturation of the latter and with that of the output currents from the transistors. <IMAGE>
