Electronic oscillator having control and regulating circuits - is applicable to energy or standby power supply units

摘要

The electronic oscillator has a regulating and control circuit and there is an unclamping circuit between it and its power stage. There is a receiver circuit which is connected, via a filter and the wiper contact of a switch, to a voltage source or to the output stage of the oscillator which is supplied from a battery d.c. source. The filter acts to smooth out high frequency and low frequency distortion. A low power auxiliary oscillator has a common d.c. supply with the main oscillator and provides an output in parallel with the power oscillator output, both oscillators are controlled from the same circuit.
