Abstract: 1,039,825. Non-contact-making relays; transistor switching circuits. MOTOROLA Inc. Aug. 4, 1964 [Aug. 15, 1963], No. 31150/64. Headings H3B and H3T. [Also in Division H2] A control or protective circuit comprises a transformer 52 having its primary winding 52a connected between an A.C. source and a load, a semi-conductor switching device 20 connected to the secondary winding 52c of the transformer for varying the impedance of the primary winding to control the flow of current to the load, and a thermistor connected to the device 20 for switching it between the conductive and non- conductive conditions. The load may be the operating coil of a contactor controlling a motor having positive temperature coefficient thermistors associated with its windings. In the arrangement shown, a semi-conductor controlled rectifier 20 is normally rendered conducting by the resultant positive bias derived from a transformer 50, a balancing resistor R 1  and the thermistor R x . The rectifier 20 and diodes 62, 64 short-circuit the secondary winding 52c so that the winding 62a is of low impedance and the contactor coil is energized. In the event of overheating, the resistance of the thermistor R x  increases and the resultant bias becomes negative rendering the rectifier 20 non-conductive so that the winding 52c is effectively opencircuited. The winding 52a now has a high impedance and effectively de-energizes the contactor coil. A further secondary winding 52b of the transformer 52 is now energized and adds to the negative bias on the gate of the rectifier 20 so that a substantial drop in temperature is necessary before the rectifier 20 will again conduct. By interchanging the resistors R 1 , R x  a negative temperature coefficient resistor may be used.

The control circuit (Fig. 2 not shown) receives "desired value" and "actual value" reference voltages (although it is current which is being maintained) and feeds difference signals Va, Vb derived from them and differing by a small amount to the circuits 13, 14 whose outputs over one cycle of the inverter output are shown in the lower part of Fig. 3 (not shown).
