Abstract

1,073,612. Automatic control of electrical power. D.F. O'BRIEN. May 3, 1965, No.18461/65. Heading G3R. Power supplied to a load, e.g. welding arc or electric motor during starting, is kept constant by a system in which the product of instantaneous current and voltage is measured. In the preferred embodiment the load current energizes an electromagnet in a Hall effect device, and a proportion of output potential is applied across the Hall plate, the resultant Hall effect voltage being compared with a reference voltage developed across a Zener diode in a transistor comparitor, and the error voltage applied as base bias on a transistor in series with the load. Mention is made of regulation by a shunt instead of series arrangement, for A. C. as well as D. C., and the use of an alternative measuring device such as a valve multiplier.
