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 graxateur of a phase, said control signal causing fradateur 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.
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.
Control apparatus for a light radiation-type rapid heating and processing device. Monday, March 26, – 3: Building security mechanical drive actuator control method, e. The converter design is developed on the base of a measurement campaign carried out at the substation.
Furthermore, if a single-phase dimmer has no practical interest and control of the thyristor gates of a three phase dimmer, from a trigger signal as the falling edge of Vmem, is also perfectly known.
Firstly, the French railways system is introduced and the interest in installing power electronic compensators in gradateuur is highlighted. Inductive proximity detector fitted with an oscillating circuit exhibiting relaxation.
The invention applies in particular to the control of heaters. Saturday, September 29, – 3: The single-phase voltage Vr across the resistor R is shown in Figure 7. This voltage Vr is found that is syncopated and includes whole alternations and isolated from the supply voltage V Vmem whenever the signal has a falling edge. Method and device for supplying a resistance graateur appliance with alternating current through selected alternations. Means for temperaturabhaengigen electronic power control of fan motors for alternating current, in particular for heating and air conditioning.
Device for supplying a plurality of resonant circuits by means of an inverter type power generator. Regulating the power delivered into resistive loads powered with alternating current is conventionally effected by means of dimmers single or three phase, generally constituted according to the distribution of the phases, by a parallel thyristors mounted head to tail or a combination thyristors and diodes. Device for supplying discharge lamps and automotive headlamp containing such a device.

Method and device for open-loop control of single-phase or multiphase A. In railway transportation, single-phase 25kVHz electrification system is widely diffused especially for high-speed railway applications.
Single phase dimmer shown in the drawing is for controlling power supplied to a resistor R of purely resistive type, for example a heating resistor.
Finally, experimental results carried out at the SNCF test platform on a 1.
In the second part, the use of CCI structures in reactive power compensation is investigated. Based on the step-down or step-up functioning mode of CCIs, two topologies of reactive power compensator are presented.
Two types of devices are implemented today on the French Railway Network: It is a 32MVA substation connected to a 90kV transmission line. Method of controlling the heating power developed in a heating element and apparatus using same. In early ages, due to its very simple diagram, there was no necessity to integrate power electronics in substations.
In the process according to the invention Vmem goes to its high logic level whenever the latch circuit 5 detects a pulse on the control signal Vcom, and returns to its low logic level when it detects a monophass pulse on the VSVN signal.
Measurements carried out on the substation site allow the compensator design and the possibility to consider real waveforms for current and voltage in numerical simulations. The present invention relates to a method of controlling a dimmer gradateir resistive loads.

Have you forgotten your login? Controlling a power converter for an automatic search of the maximum power point. Wednesday, June 27, – 2: The switching device – e. The device described in this document, however, is very complex since it requires to achieve the objectives listed above, to provide a digital control circuit based on a microprocessor controlling all three phases 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.
However, for the last decade, the interest in power electronic equipments raised since they can provide the solution for network optimization when traffic increases or when a difficulty is foreseen for a substation implementation.
The manuscript is developed through three main parts: Giuliano Raimondo 1 Details. As a case study, the substation of Evron is considered.
