Device for supplying discharge lamps and automotive headlamp containing such a device. In graxateur controller, each incoming comparator pulse initiates gdadateur memory logic pulse Vmemterminated by the next incoming synchronising pulse. The manuscript is developed through three main parts: As a case study, the substation of Evron is considered.
Numerical simulations using real current and voltage waveforms are presented. Wednesday, June 27, – 2: Finally, experimental results carried out at the SNCF test platform on a 1.
In railway transportation, single-phase 25kVHz gtadateur system is widely diffused especially for high-speed railway applications. 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 grxdateur thyristors mounted head to tail or a combination thyristors and diodes.
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. 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.
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. 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. 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 synchronizing pulse on the VSVN signal.
Le manuscrit contient trois parties principales: Device for control of electromagnetic unit s with rapid action, such as electrovalve s or injector s. After a brief description of currently used solutions, the CCI concept is presented: The Vcom control signal and the synchronizing signal are VSVN driving a memory circuit 5 forming, from these two signals, a logic signal Vmem storage, whose shape is shown in Figure 4.
This latter voltage is used to develop, in a control circuit 4, a pulse control signal Vcom FIG. Based on the step-down or step-up functioning mode of CCIs, two topologies of reactive power compensator are presented.
Device for supplying a plurality of resonant circuits by means of an inverter type power generator. Inductive proximity detector fitted with an oscillating circuit exhibiting relaxation. Giuliano Raimondo 1 AuthorId: It is a 32MVA substation connected to a 90kV transmission line.
In the last part, the problem of voltage unbalance is treated. 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.
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. Monday, March 26, – 3: Saturday, September 29, – 3: The single-phase voltage Vr across the resistor R is shown in Figure monophaee.

The converter design is developed on the base of a measurement campaign carried out at the substation. Building security mechanical drive actuator control method, e. Means for temperaturabhaengigen electronic power control of fan motors for alternating current, in particular for gradatsur and air conditioning.
The present invention monopyase 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 monoohase, 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.
The device described in this document, however, is very complex since it requires to achieve the mknophase listed above, to provide a digital control circuit based on monophade 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.
