摘要： An apparatus for controlling AC supply switches is disclosed, in which the AC supply is switched between a lamp load (1) by means of a power triac (2) and a circuit which converts the AC supply voltage to a DC voltage by using a bridge circuit and a voltage limiting circuit for powering auxiliary control circuits. A triggering circuit which actuates power triac (2) in response to a switch control signal (21) comprises an opto-coupled triac driver (14). The apparatus can also be adapted to perform AC supply switching for multiple lamp loads.

摘要： An electronic AC voltage stabilizer using a class B amplifier output stage which is fed by a full-wave rectified sinewave voltage. The input voltage to (the phase inverter of) the class B amplifier output stage is kept in phase with the aforesaid sinewave voltage, which causes the power losses over the output stage to be very low. As compared to other electronic AC stabilizers the apparatus according to the invention offers high efficiency and simplicity. The AC stabilizer can easily be converted into a true UPS by adding a battery which by intermediary of a battery interface connects the conditioned battery voltage to the push pull amplifier output stage when the network fails.

摘要： A circuit arrangement for the control of AC power supplied to a load (10) comprises a silicon-controlled rectifier (11) forming with the load a series circuit which is connected to an AC power source via terminals (12, 13). A series circuit comprising a resistor (14) and a capacitor (15) is connected in parallel with the silicon-controlled rectifier. The connecting point between the resistor (14) and the capacitor (15) is connected to the gate of the silicon-controlled rectifier via a trigger device, for example an AC diode referred to as Diac. A capacitor (17), a diode (18) and a capacitor (19) form a series circuit which is connected in parallel with the capacitor (15). By means of a discharge circuit or in another suitable way the voltage over the capacitor (19) can be kept at a desired level. Thereby, the conduction angle of the silicon-controlled rectifier may be set within wide limits, practically between 0` and 180` in every controlled half-cycle of the supply voltage.

摘要： A method for controlling the power of a load (1) powered from a source of AC voltage U having a period T using a phase control system, wherein, for a predetermined set power, a sequence of an integer p of elements, where p is greater than 1, is periodically delivered to said load (1), each element, numbered i, of the sequence being characterised by an integer ni with a half-period T/2 during which the AC voltage U is switched according to a series of different phase angles alpha i from alpha 1 to alpha n corresponding to respective durations ti from t1 to tn during which the load (1) is cut off from the power supply. The phase angles alpha i of element i and alpha i+1 of element i+1 have similar repetitive values so that the mean current is zero over a complete cycle.

摘要： A supply voltage circuit having an input for connecting an input alternating voltage and an output for tapping off an output power of predetermined value. Said circuit comprises a zero crossing detector connected to the input and which delivers zero crossing pulses at the zero crossings of the input alternating voltage. The zero crossing pulses control a timing circuit, which after a time period following the zero crossing pulses and corresponding to the predetermined value of the output power, supplies control pulses to the control circuit of a triac circuit interconnected between the input and the output of the supply voltage circuit. A set and reset circuit is connected between the zero crossing detector and the timing circuit for resetting and setting the timing circuit prior to the zero crossings of the input alternating voltage.
