ABSTRACT:
A self-oscillating inverter circuit wherein the inversion frequency can be controlled by way of providing a controllable flow of electrical power to a resistor heating means that is thermally coupled to a saturable magnetic ferrite transformer used in the inverter's positive feedback loop. By way of its saturation characteristics, the saturable transformer determines the inversion frequency. These saturation characteristics are substantially influenced by temperature; which therefore provides the basis for controlling the frequency by controlling the flow of electrical power to the resistor heating means.
