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 monophaxe.
Reactive Power compensators and Voltage Unbalance compensators. Monday, March 26, – 3: The manuscript is developed through three main parts: This latter voltage is used to develop, in a control circuit 4, a pulse control signal Vcom FIG. Single phase dimmer shown in the drawing is for controlling power supplied to a monophwse R of purely resistive type, for example a heating resistor.
The invention applies in particular to the control of heaters. 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 monlphase 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.
In the last part, the problem of voltage unbalance is treated. Device for control of electromagnetic unit s with rapid action, such as electrovalve s or injector s.
Single phase Power control TE10P
In railway transportation, single-phase 25kVHz electrification system is widely diffused especially for high-speed railway applications.
As a case study, the substation of Evron is considered. Building security mechanical drive actuator control method, e. Le manuscrit contient trois parties principales: Graeateur 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 monophasee phases, in particular their direction of change, the phases and the direction of change of said voltages being switched after a series gradateurr six successive trips of the supply load.
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.
In early ages, due to its very simple diagram, there was no necessity to integrate power electronics in substations.
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. Wednesday, June 27, – 2: 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. The present invention relates to a method of controlling a dimmer for resistive loads.
Method of controlling the heating power developed in a heating element and apparatus using same. Saturday, September 29, – 3: 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.
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. The converter design is developed on the base of a measurement campaign carried out at the substation.
The single-phase voltage Vr across the resistor R is shown in Figure 7. After a brief description of currently used solutions, the CCI concept is presented: It is a 32MVA substation connected to a 90kV transmission line. The switching device – e.
This thesis presents an investigation into new topologies based on the concept of “Chopper Controlled Impedances” CCI. Firstly, the French railways system is introduced and the interest in installing power electronic compensators in substations is highlighted. Compared to existing solutions, the new topologies show interesting features in terms of grzdateur losses reduction and volume of reactive components.
Controlling a power converter for an automatic search of the maximum power point. 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.
Inductive proximity detector fitted with an oscillating circuit exhibiting relaxation. Method of soft-starting a switching power supply having time-based pulse triggering control. In the controller, moophase incoming comparator pulse initiates a memory logic pulse Vmemterminated by the next incoming synchronising pulse.
