Abstract

1,113,411. Transistor switching circuits for inductive loads. SOCIETE ALSACIENNE DE CONSTRUCTIONS ATOMIQUES DE TELECOMMUNICATIONS ET D'ELECTRONIQUE " ALCATEL." 16 July. 1965 [17 July, 1964], No. 30330/65. Heading H3T. [Also in Division H2] Rapid energization of a coil is effected by connecting one end of the coil through a first switch to a potential source to provide the build-up of current and through a second switch to a lower potential to provide a maintaining current. The inductive load L, Fig. 9, is rapidly energized by applying voltages to AB and MN to render transistors Q 2 , Q 4 and Q 3 conductive. Transistor Q 3 applies a high voltage to inductor L to rapidly establish the energizing current therein after which it becomes non-conducting and the current is maintained through transistor Q 3 from a lower voltage source E 2 . The voltage for rendering Q 2 non-conductive may be derived from across a series resistor such as R (Fig. 5, not shown). Q 2 may be replaced by a semi-conductor rectifier fed from a capacitor so that when the capacitor has discharged into the inductor the voltage across the thyristor is insufficient to maintain conduction. The capacitor is recharged from the high-voltage source through a resistor or resonantly through an inductor (Figs. 11 and 13, not shown). Transistor Q 3 may also be replaced by a thyristor preferably having a turn-off electrode as well as a normal gate (Fig. 13, not shown). Where energization in either of two polarities is required, two similar circuits one comprising transistors complementary to the other may be connected across the load to operate alternatively (Fig. 14, not shown), or two similar circuits may be connected to oppositely poled windings (Fig. 16, not shown). It is also possible to utilize a permanent current source of one polarity and two sources of the opposite polarity connected in accordance with the invention (Figs. 15 and 17, not shown). In Fig. 9 a diode D 1 protects transistor Q 3 against over-voltage during energization and a Zener diode D 2 affords protection during de-energization.
