Patent GB-1140614-A (GB)
Title: Electronically controlled vending machine
IPC: G07F5/18
Filed: 1966-11-11
Abstract: 1,140,614. Thyristor switching circuits. DAGMA DEUTSCHE AUTOMATEN - und GETRANKE - MASCHINEN G.m.b.H. & CO. 11 Nov., 1966 [23 Dec., 1965], No. 50620/66. Heading H3T. A thyristor fired by control pulses at its gate has an anode/cathode supply of rectified A.C. form, and a reactance is associated with the gate or supply circuit so that at the zero point of the rectified A.C. supply the thyristor is maintained conducting or is refired by the next control pulse. In the simplest form the reactance may be an electrolytic capacitor across the thyristor and load (Fig. 1, not shown) to maintain the voltage above the critical minimum, or an inductance in series with the thyristor and load (Fig. 3, not shown) to maintain the current above the holding value. A Zener diode may be shunted across the inductance to prevent damage by induced peak voltages. In Fig. 3 the reactance is a capacitor 8 in the gate circuit, the terminals 1/2 being connected to the rectified A.C. supply. The thyristor is fired by control pulses at 6, and the capacitor 8 becomes charged to the voltage across the load 5. When the thyristor has cut off at the zero point of the supply, it will be re-fired when the supply voltage rises again, due to discharge of capacitor 8 through diode 11 and the gate. The thyristor can be cut off by negative pulses at 7, which discharge capacitor 8, and will then be re-fired by another pulse at 6. In a modification (Fig. 4, not shown) the capacitor 8 and diode 10 are interchanged, and the effect is augmented by an inductance in series with the load 5. The circuit is used to perform a switching function in a vending machine.
