Abstract

The DC-AC convertor has at least two control electrode switching devices. It also has modulating circuits designed to supply to the control electrodes a control signal which triggers conduction of the switches. The control signal from the modulating circuit is voltage pulse width modulated at a determined frequency. This frequency is considerably greater than the convertors output frequency. The converter has filters designed to filter the signals from each of the switches. The filters eliminate the signals having the modulation frequency and transmit the devised output frequency. The first and second switches include an arrangement of two transistors and a transformer which form a push pull circuit. The control electrode of each of the switches being the base of the corresponding transistor. The filter circuit is arranged in the primary winding of the push pull circuit transformer.
