Reactive Power compensators and Voltage Unbalance compensators. Control apparatus for a light radiation-type rapid heating and processing device. Wednesday, June 27, – 2: The invention applies in particular to the control of heaters. Method and apparatus for controlling a-c power by means of thyristors for a resistance-type electric furnace.
Device for supplying discharge lamps and automotive headlamp containing such a device. Monday, March 26, – 3: This latter voltage is used to develop, in a control circuit 4, a pulse control signal Vcom FIG. Numerical simulations using real current and voltage waveforms are presented.
The present invention relates to a method of controlling a dimmer for resistive loads. Method and device for supplying a resistance electrical appliance gradateeur alternating current through selected alternations. In the controller, each incoming comparator pulse initiates a memory logic pulse Vmemterminated by the next incoming synchronising pulse. As a case study, the substation of Evron is considered. However, for the last decade, grradateur interest in power electronic equipments raised since they can provide the solution for network optimization when traffic increases or when a difficulty is foreseen geadateur a substation implementation.
Each such termination generates gate pulses iG,iG’causing one complete mains voltage cycle to be applied to the load. Method of soft-starting gradatuer switching power supply having time-based pulse triggering control.
Based on the step-down or step-up functioning mode of CCIs, two topologies of reactive power compensator are presented. The present invention aims to provide a control method much simpler and less expensive from a single or three phase dimmer monophaee 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, gradqteur control signal causing the switching of a single alternation of the supply voltage on said monoophase from the zero crossing, or on the rising or falling edge of said supply voltage.
It is a 32MVA substation connected to a 90kV transmission line. 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.
Le manuscrit contient trois parties principales: Static power supply device of an electrofilter for electrostatic dust precipitation.
After a brief description of currently used solutions, the CCI concept is presented: The manuscript is developed through three main parts: 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.
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. Means for temperaturabhaengigen electronic power control of fan motors for alternating current, in particular for heating and air conditioning.
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.

Finally, experimental results carried out at the SNCF test platform on a 1. 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.
Triac firing control circuit for inductive loads – uses supply and anode voltage sensing to control short gate pulses after zero crossings of voltages for low energy firing. 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.
Two types of devices are implemented today on the French Railway Network: The switching device – e. The single-phase voltage Vr across the resistor R is shown in Figure 7. Building security mechanical drive actuator control method, e.
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. Regulating the power delivered into resistive loads powered with alternating current monophasd conventionally effected by means of dimmers single or three phase, generally constituted according to the distribution of the phases, by a parallel thyristors mounted graeateur to tail or a combination thyristors and diodes.
In the second part, the use of CCI structures in reactive power compensation is investigated. Device for control of electromagnetic unit s with rapid action, such as electrovalve s or monpphase s. In comparison to a monophasr 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.
Firstly, the French railways system is introduced and the interest in installing power electronic compensators in substations is highlighted. Inductive proximity detector fitted with an oscillating circuit exhibiting relaxation. Measurements carried out on the substation site allow the compensator design and the possibility to consider real waveforms for current and voltage in numerical monophade. In early ages, due to its very simple diagram, there was no necessity to integrate power electronics in substations.
Method and device for open-loop control of single-phase or multiphase A. Giuliano Raimondo 1 AuthorId: 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.
Controlling a power converter for an automatic search of the maximum power point. In railway transportation, single-phase 25kVHz electrification system is widely diffused especially for high-speed railway applications.
