Abstract

1,093,316. Sawtooth generators. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. April 4, 1966 [April 7, 1965; July 9, 1965], No. 14854/66. Heading H3T. [Also in Division G3] The voltage from a source 14 (e.g. a pulse generator) applied to a temperature-dependent load 13 (e.g. an inductance producing a sawtooth current) is maintained constant by controlling a series transistor 2 in dependence upon load voltage variations as detected by a bridge network constituted by resistors 15, 16, 17 and a circuit 8 arranged to compensate for temperature changes. The circuit 8 comprises a transistor associated as shown with a voltage divider 10, 11 and the emitter/collector voltage of the transistor serves as the reference voltage for the bridge network, the output from which is applied, over an amplifying transistor 18, as a control signal to the base of transistor 2. The bridge network may include a resistor 19, carrying the load current, to compensate for load fluctuations. The current can also vary because of temperature changes in the transistor 2 and the load 13, resulting in an incorrect control action. The Specification explains how the values of the resistors 10, 11 are related to the base/emitter input impedance and the base/ emitter threshold voltage of the transistor 9 in order to compensate for the temperaturedependent variations in the load current. The resistor 10 may itself be in the form of a voltage divider having its tapping connected over a resistor (21) to the supply voltage (Fig. 3, not shown) so that the base/emitter voltage of transistor 9 may be adjusted independently of the values of resistors 10 and 11. The pulses may be applied to the base of the transistor 2.
