Power controller having current limited rms voltage regulated output

A power controller converts a line voltage to an RMS load voltage for a lamp, and includes a switch and a microcontroller that operates the switch to define the RMS load voltage. The microcontroller senses a load voltage of the lamp, compares the sensed load voltage to a reference RMS voltage, and operates the switch in response to the comparison so that the RMS load voltage is substantially constant at the reference RMS voltage over an operating range of the line voltage and so that the RMS load voltage decreases with decreasing line voltage at line voltages less than the operating range. The operating range of the line voltage is defined to have a minimum that is a non-zero line voltage at which a load current is a predetermined maximum. The voltage conversion circuit may be a phase clipping circuit or a pulse width modulation circuit.

Circuit arrangement for radio interference suppression in control units based on the phase control principle

Zur Funkentstörung von Spannungsregelschaltungen, die nach dem Phasenanschnittsprinzip arbeiten, wird eine Entstördrossel in Reihe zu dem als Regelglied arbeitenden Halbleiterschalter (T) gelegt. Die aus dem Halbleiterschalter (T) und der Entstördrossel (Dr1) bestehende Reihenschaltung liegt im Ladestromkreis und wird von einem ebenfalls zur Entstörung dienenden Kondensator (C) überbrückt. Dieser Kondensator (C) hat nachteilige Auswirkungen, wenn die den Zündzeitpunkt des Halbleiterschalters beeinflussende Steuerschaltung ferngesteuert werden soll. Hierzu wird, ausgehend von einem Sender der Netzspannung, eine relativ hochfrequente Steuerspannung überlagert, für die der Kondensator einen niedrigen Widerstand und damit eine hohe Last bedeutet. Durch das Einfügen einer weiteren Drossel in den Lastkreis wird der Widerstand für höhere Frequenzen größer und damit die Belastung des Senders herabgesetzt. Die Verwendung eines Ferritkernes für die zusätzliche Drossel ermöglicht eine relativ große Induktivität bei kleinen Abmessungen. For radio interference suppression of voltage control circuits that work according to the phase control principle, an interference suppression choke is placed in series with the semiconductor switch (T), which works as a control element. The series circuit consisting of the semiconductor switch (T) and the interference suppression choke (Dr1) is located in the charging circuit and is bridged by a capacitor (C), which is also used for interference suppression. This capacitor (C) has disadvantageous effects if the control circuit influencing the ignition timing of the semiconductor switch is to be remotely controlled. For this purpose, starting from a transmitter of the mains voltage, a relatively high-frequency control voltage is superimposed, for which the capacitor means a low resistance and thus a high load. By adding another choke to the load circuit, the resistance for higher frequencies increases and the load on the transmitter is reduced. ...

Power line control system

The present invention provides a system and a method for controlling electrical devices connected to an AC power line by means of control signals transmitted over the AC power line. The control system consists of a transmitter apparatus and a receiver apparatus. The transmitter apparatus generates, and transmits via an AC power line, multiple voltage pulses during any one-half cycle of the AC power line voltage. The multiple voltage pulses act as control signals for any electrical device that is sought to be controlled, or a "slave" device. The receiver apparatus is simultaneously coupled to the slave device and the AC power line for receiving and, if necessary, decoding the voltage pulses sent by the transmitter apparatus. The receiver apparatus in turn generates a command signal that controls the slave device's operation.

Discharge lamps supply from three phase lines - provides remote switching of inductors from neutral line using auxiliary and main inductances

The system supplies and switches cold cathode discharge lamps fed from a three-phase supply. The switching of shunting inductors is intended to reduce the power dissipated. Switching control is remote and transmitted by the neutral line. Each lamp circuit has a main and auxiliary inductance. The auxiliary inductance is shunted by the control circuit (4) fed from a clock source. Shunting is achieved by switching into conduction a triac (30) which is fed from a series diode (21)-diac (27)-resistor chain shunted to one phase line (6) by capacitors. The diac-triac circuitry acts as a controlled oscillator providing the gating power. Protection against overvoltage is provided by a parallel DC circuit (28,90) across the triac.

Control circuit for triac switch - has RC circuit making turn:on independent of trigger pulse duration

The control circuit, for a triac switch typically for one which switches a heating element on and off, has an RC circuit between the triggering circuit and the triac gate to make the actual turn-on pulses applied to the triac independent of the duration of the pulses leaving the triggering circuit. The RC circuit consists of a first transistor coupled by its collector to the triac gate and over a series timing resistor and capacitor to the base of a complementary second transistor. The second transistor is driven into saturation by the triggering circuit and in turn causes the first transistor to turn on after the time determined by the RC circuit has elapsed.

Process and device for controlling single-phase or multiphase a.c. controllers

In the open-loop control of A.C. power controllers through the phasa-angle control of semiconductor valves (4), the chronological sequence of the firing signals (Z) for the semiconductor valves (4) is determined by reference signals (X).

In addition, a device for implementing the method is specified.
