Title: Limitation of power dissipation in electronic components
IPC: H02H3/02
Filed: 1974-02-07
Abstract: 1460853 Protecting transistors against overload SIEMENS AG 7 Feb 1974 [7 Feb 1973] 5747/74 Heading H2K [Also in Division H3] An electronic component 16 is protected against overcurrent by a detector 25 which on detection of a load current exceeding a threshold value I 1  operates an interrupter 17, 18, 15, 16 to periodically interrupt the load current, whilst a current limiter 29 limits the magnitude of the current through the component 16 to a level I 2  which is greater than the threshold level I 1  so limiting the power dissipation in the component. The interrupter includes a switching circuit 17, 18 which exhibits hysteresis, switching between first and second states in response to the voltage across a capacitor 22 increasing to a first threshold voltage U 1  and descreasing to a second threshold voltage U 2  respectively. The capacitor 22 is charged and discharged cyclically by a switch 25 responsive to the overcurrent. When an overcurrent occurs, the voltage across the capacitor 22 reaches the first threshold U 1  after a time t 1 , whereupon transistors 18 and 20 turn on and transistors 15, 17 and 19 turn off. This turns off driver transistor 15 and hence the output transistor 16 for a time t 2 . During the time t 2  the capacitor 22 discharges via a transistor 27 until the capacitor voltage reaches the second threshold U 2  whereupon the transistors 18 and 20 turn off and the transistors 15, 16, 17 and 19 turn on again. A limiter transistor 29 controls the transistor 15 to limit drive of the output transistor 16 during time t 1 . In a simplified embodiment (Fig. 2, not shown) if the load current rises above the threshold I 1  a switch (5) is closed to initiate charging of a capacitor (6). After a delay t 1  the capacitor voltage reaches a value U 2  such that a switching circuit (9) changes state, operating a relay (10) to open a contact (11) in the load path and close a contact (12) in a discharge path for the capacitor. The switching circuit (9) switches back when, after a further delay t 2 , the capacitor voltage has fallen to a value U 1 , whereupon the relay (10) reconnects the load path. The circuits may be used for driving capacitive loads or incandescent lamps.

In a circuit arrangement for the control of power taken from A.C. supply lines 1 by a load 2 and comprising two parallel backto-back connected mercury pool ignition discharge valves 3, 4 serially connected into one of the supply lines, the ignition voltage for each ignition electrode is derived from the voltage subsisting between the ignitron main electrodes and is increased by a booster transformer 5 whose primary winding is shunted across the ignitrons and whose secondary winding in series with a switch 6 is connected between two points each of which forms the junction between two respective unidirectional conductive members 31, 32 and 41, 42 serially connected between the ignition electrode and cathode of the respective ignitrons. The members 31, 32, &c. may be metal rectifiers and those 31, 41 may each have their threshold of conductivity above the voltage which subsists in the ignition circuit after ignition has been effected to prevent current flow in such circuit when its ignitron is conductive. By connecting the transformer secondary winding, through the rectifiers 32, 42, across the ignitrons 3, 4 its voltage is combined with that of the latter by an auto-transformer effect. A shifting of the ignition point can be obtained by providing tappings on the transformer.
