Abstract: A circuit for controlling the power in a load supplied by an A.C. voltage and directly connected to a first terminal of application of the A.C. voltage, including two isolated-gate bipolar transistors, connected in anti-parallel between a second terminal of application of the A.C. voltage and the load; circuitry for detecting the zero crossing of the A.C. supply voltage in a first direction; circuitry for generating, at each period of the supply voltage, a pulse of predetermined duration for controlling a first one of said transistors, the time of occurrence of the pulse being conditioned by the detection of the zero crossing of the A.C. voltage and by a desired power reference setting a variable delay of occurrence of the pulse with respect to the detected zero crossing; and circuitry for inverting and transferring said pulse to the second transistor.

Abstract: Dimmer has two switches (2, 3), each controlled by driver circuit (6, 7) associated with supply circuit. Each supply circuit has capacitor (C1, C2) in series with rectifying diode (D1, D2), and with capacitor and rectifying diode placed in parallel with voltage limiting Zener diode (DZ1, DZ2). Both supply circuits are connected by capacitor (C). Respective supply voltages of driver circuits are provided across respective capacitors of each supply circuit.

Abstract: The circuit has a coupling circuit with a node attached to a collector of a NPN transistor whose emitter is connected to a voltage (G1), and base receives an output of a microprocessor. Each of the node and voltage (G2) is attached to respective capacitor terminals. The node is attached to an emitter of a PNP transistor whose base is connected to the former transistor and collector is connected to the terminal of the triac. A diode connects the voltage that feeds the microprocessor to the coupling circuit. An Independent claim is also included for an operating circuit of an electromagnetic relay.

Abstract: The circuit (25) has comparators (37, 39) assigned to halfwaves of signs of an AC power supply to receive reference voltages setting respective thresholds on reference inputs (40, 43). An input stage provides a voltage proportional to a voltage across a bidirectional switch to respective read inputs of the comparators. A resistor (41, 44, 45) introduces a voltage drop between terminals of the switch unit and inputs.
