Title: A four-terminal circuit
IPC: H02H11/00
Filed: 1961-10-20
Abstract: 925,527. Semi-conductor switching circuits. LICENTIA PATENT - VERWALTUNGSG.m.b.H. Oct. 20, 1961 [Nov. 10, 1960], No. 37693/61. Class 40 (6). A circuit which permits an input voltage applied in either polarity between input terminals 1 to appear selectively with either the same or reversed polarity between output terminals 2 comprises two pairs of conductors 11, 12 and 31, 32 interconnecting the input and output terminals with the sense of the connections performed by one pair reversed with respect to that of the other and connected between each pair of conductors controllable diode switching means 13 and 33 whereby transmission through any one pair of conductors may be prevented. Each switching means comprises a rectifier bridge which is connected in each pair of conductors between the junction points of two equal resistors arranged in series in each conductor of the pair. Transistors 14, 34 control conduction through the respective rectifier bridges 13, 33. By making all the resistors equal it can be ensured that no output appears at 2 when neither transistor is energized. A voltage source may be inserted in the collector circuit of each transistor, Fig. 3 (not shown); this then biases the rectifier bridge to be fully conducting when its respective transistor conducts, thus eliminating the dead-zone that tends otherwise to occur for small input voltages. In a further embodiment, Fig. 4, switching on transistor 24 or 44 permits alternating current from source 21 or 41 to flow, thus energizing rectifier bridge 23 or 43 which produces a unidirectional voltage for controlling the switches 13 or 33. Zener diodes 26 and 46 are provided for isolating bridges 13 and 23 and bridges 33 and 43 when the respective transistors are not conducting. Specification 717,123 is referred to.
