Abstract

1,102,494. Converting circuits. E. K. COLE Ltd. 21 March, 1966 [20 March, 1965], No. 11939/65. Heading H2F. [Also in Division H3] A relaxation oscillator used in an A.C. to D.C. converter has its output amplitude stabilized against variations in output impedance by means of a Zener diode 18 connected across the collector-emitter path of the oscillator transistor 4 so as to conduct when the transistor is cut off. The circuit provides an increase in output with a decrease in supply voltage 7 and in order to compensate for this part of the supply voltage may be injected in opposition into the output circuit by replacing link 19 with a potentiometer circuit 20. A plurality of outputs may be provided, each taken from a separate secondary winding 3, and each having its own potentiometer circuit.
