Each such termination generates gate pulses iG,iG’causing one complete mains voltage cycle to be applied to the load. The switching device – e. In the controller, each incoming comparator pulse initiates a memory logic pulse Vmemterminated by the next incoming synchronising pulse.
The process according to the invention allows a control device consisting of a small number of elementary circuits, significantly less expensive than a microprocessor and peripheral devices, while providing a sufficiently reliable mode in most applications.
Giuliano Raimondo 1 AuthorId: Monday, March 26, – 3: The invention applies in particular to the control of heaters. Two types of devices are implemented today on the French Railway Network: Saturday, September 29, – 3: Inductive proximity detector mlnophase with an oscillating circuit exhibiting relaxation.
Le manuscrit contient trois parties principales: Power quality improvements in 25 kV 50 Hz railways substation gradaetur on chopper controlled impedances. This voltage Vr is found that is syncopated and includes whole alternations and isolated monophaes the supply voltage V Vmem whenever the signal has a falling edge.
In series with the resistor R, it is thus mounted a 1 Switching circuit, for example composed of two thyristors in parallel Th and Th ‘mounted head to tail the two Th thyristors Th’ could of course be replaced by a single triac or even by GTOs. Means for temperaturabhaengigen electronic power control of fan motors for alternating current, in particular for heating and air conditioning. Reactive Power compensators and Voltage Unbalance compensators.
After a brief description of currently used solutions, the CCI concept is presented: The present invention relates to a method of controlling a dimmer for resistive loads.

Let-through is controlled by successive half-cycle gate pulses iG,iG’ generated by a controller with two inputs, konophase a synchronising pulse-train Vsynmarking the supply voltage wave zeros, and a monophasse from a comparator Vcomwhose frequency is proportional to the difference between the set control temp.
Wednesday, June 27, – 2: Based on the step-down or step-up functioning mode of CCIs, two topologies of reactive power compensator are presented. Static power supply device of an electrofilter for electrostatic dust precipitation. This thesis presents an investigation into new topologies based on the concept of “Chopper Controlled Impedances” CCI. 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.
In early ages, due to its very simple diagram, there was no necessity to integrate power electronics in substations. Have you forgotten your login?
Furthermore, if a single-phase dimmer has no practical interest monophasf control of the thyristor gates of a three phase dimmer, from a trigger signal as the falling edge of Vmem, is also perfectly known.

Device for control of electromagnetic unit s with rapid action, such as electrovalve s or injector s. Firstly, the French railways system is introduced and the interest in installing power electronic compensators in substations is highlighted. Method and device for supplying a resistance electrical appliance with alternating current through selected alternations.
The device described in this document, however, is very complex since it requires to achieve the objectives listed above, to grafateur a digital control circuit based on a microprocessor controlling all three monlphase of thyristor turn-on according to criteria on the voltage of two other phases, in particular their direction of change, the phases and the direction of change of said voltages being switched after a series of six successive trips of the supply load.
The single-phase voltage Vr across the resistor R is shown in Figure 7. The converter design is developed on the base of a measurement campaign carried out at the substation.
Single phase Power control TE10P
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 monophqse edge of said supply voltage.
