ABSTRACT:
An inverter circuit is disclosed in which the efficiency of the inverter is improved by interposing a small transformer winding between the transistors in a Darlington pair which are used to switch the primary current of the inverter. The winding couples energy from the transformer into the Darlington pair at a polarity which opposes the characteristic junction potential of the output transistor. This substantially reduces the saturation voltage of this output transistor. The regulation of the output voltage is improved by detecting the RMS value of the output voltage and using the detected RMS value of the output voltage for controlling the width of pulses applied to the primary of the transformer of the inverter.
