Switching circuitry for use with an autotransfortner for the smooth transition of voltage output from a circuit of either d.c. or a.c., between a higher and a lower voltage. The circuit includes at least one, preferably two, variable resistors (13) comprising a first solid state switch (10), an inductor (11) and a resistor (12), in which the variable resistor (13) is connected to the conductance side of the switch and wherein the circuit is connected to the voltage ouput of an autotransformer. If the solid state switch used are FETs the variable resistor (13) is placed within a bridge rectifier (D2-D5). Transition time for movement of the voltage between two levels is approximately one second.

Circuit de commutation d'autotransformateur, permettant une transition douce de la tension de sortie d'un circuit c.c. ou c.a. entre un niveau haut et un niveau bas. Le circuit comprend au moins un, et de préférence deux, résistances variables (13) comprenant un premier commutateur à semi-conducteurs (10), une bobine d'induction (11) et une résistance (12), la résistance variable (13) étant connectée au côté conductance du commutateur, et le circuit étant connecté à la sortie de tension d'un autotransformateur. Si les commutateurs à semi-conducteurs utilisés sont des FET, la résistance variable (13) est placée à l'intérieur d'un pont redresseur (D2-D5). Le temps nécessaire au passage de la tension entre deux niveaux est d'environ une seconde.
