Abstract: A DC-AC converter includes a transformer with its primary winding in series with a transistor across the terminals of a DC voltage source. A resistor is connected between the emitter and base of the transistor and a coupling capacitor connects a coupling winding of the transformer to the base of the transistor. An auxiliary DC voltage source is included in the connection between the emitter and the resistor so that the converter is less sensitive to variations in the DC source voltage.
