Abstract: The invention relates to a generator for producing control signals for striking the controllable rectifiers of a three-phase inverted converter having common quenching means. The generator is a slide-type impulse-storing type of device which is actuated in synchronism with quenching impulses and has six bistable stages. The output of the third stage is applied to the input of the first stage by way of an inverter. Each stage is associated with one of the controllable rectifiers and the control signals transmitted are dependent upon the switching conditions of the stages.

Abstract: The invention relates to a step switch assembly which switches power on and off in a stepwise manner in dependence upon the upper and lower limiting values of a control signal. The switch assembly may be used for operating in a stepwise manner a bank of units such as motors wherein each motor, or group of motors, represents a portion or part of the total available capacity of a system such as air conditioning system. The step switch assembly includes a reversible counter, a transmitter for sending digital impulses to the counter, and power stages which are switchable on and off in dependence upon information stored at the counter output points.

Abstract: A GENERATOR CONTROLS A THREE PHASE CONVERTER HAVING SIX CONTROLLABLE RECTIFIERS AND A COMMON QUENCHING CONTROLLABLE RECTIFIER. A FREQUENCY EMITTER IS CONTROLLED BY AN INPUT VOLTAGE AND EMITS A CONTROLLED FREQUENCY WHICH IS SIX TIMES THE THREE PHASE FREQUENCY. THE FREQUENCY EMITTER CONTROLS THE COMMON QUENCHING RECTIFIER AND ALSO CONTROLS A THREE STAGE ANNULAR COUNTER. THE THREE OUTPUTS OF THE ANNULAR COUNTER CONTROL THREE BISTABLE MULTIVIBRATOR FREQUENCY DIVIDERS, EACH HAVING TWO OUTPUTS. THE OUTPUT OF EACH FREQUENCY DIVIDER IS CONNECTED TO A GATE CIRCUIT WHICH IN TURN CONTROL ONE OF THE SIX CONTROLLABLE RECTIFIERS. A CORRECTION CIRCUIT INTERCONNECTS THE THREE MULTIVIBRATORS TO INSURE THE PROPER SEQUENCY OF FIRING OF THE SIX CONTROLLABLE RECTIFIERS.
