Country of ref document: REF Ref document number: This seller is currently away until 03 Jan,and isn’t processing orders at this time. Method and apparatus for preventing multiple attempted firings of a semiconductor switch in a load control device. Returns are accepted within 7 working days after receipt. GB Ref legal event code: Let-through is controlled by successive half-cycle gate pulses iG,iG’ generated by a controller with two inputs, – a synchronising pulse-train Vsynmarking the supply voltage wave zeros, and a pulse-train from a comparator Vcomwhose frequency is proportional to the difference between the set control temp.


The present invention aims to provide a control method much simpler and less expensive from a single or three phase dimmer for supplying resistive loads, using a control syncopated by synchronized isolated alternation of the supply voltage switching circuits said loads, said method being characterized in that it generates a control pulse signal whose frequency is proportional to the mean power supplied to the load of a phase, said control signal causing the switching of a single alternation of the supply voltage on said phase from the zero crossing, or on the rising or falling edge of said supply voltage.

Triac firing control ttiphase for inductive loads – uses supply and anode voltage sensing to control short gate pulses after zero crossings of voltages for low energy firing.

Please enter a number less than or equal gradareur 2. In comparison to a control by wave trains which would provide for, in the same case, a conduction of the thyristors of 3 successive alternations followed by 4 periods of non-conduction, it is understood that the ripple of the average voltage or average current, is less.
