Eurotherm – Free CAD models – Single phase Power control TE10P – TraceParts
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.
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. Method and device for supplying a resistance electrical appliance with alternating current through selected alternations.
It is equipped by a 60MVA single phase transformer with the primary side connected to a kV transmission line. Compared to existing solutions, the new topologies show interesting features in terms of semi-conductor losses reduction and volume of reactive components. Monday, March 26, – 3: Have you forgotten your login? The present invention relates to a method of controlling a dimmer graxateur resistive loads.
Single phase Power control TE10P
Control apparatus for a light radiation-type rapid heating and processing device. 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.
However, for the last decade, the interest in power gadateur 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 switching device – e.
The invention applies in particular to the control of heaters. Two types of devices are implemented today on the French Railway Network: In the process according to the invention Vmem goes to its high logic level whenever the latch circuit 5 detects a pulse on the monophhase signal Vcom, and returns to its low logic level when it detects a synchronizing pulse on the VSVN signal.
Each such termination generates gate pulses iG,iG’causing one complete mains voltage cycle to be applied to the load. Device for control of electromagnetic unit s with rapid action, such as electrovalve s or injector s.
The single-phase voltage Vr across the resistor R is shown in Figure 7.
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. 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. In the second graateur, the use of CCI structures in reactive power compensation is investigated. 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.
Controlling a power converter for an automatic search of the maximum power point. Static power supply device of an electrofilter for electrostatic dust precipitation. 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.
Numerical simulations using real current and voltage waveforms are presented. 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.
Inductive proximity detector fitted with an oscillating circuit exhibiting relaxation. 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.
Giuliano Raimondo 1 Details.
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.
After a brief description of currently used solutions, the CCI concept is presented: Firstly, the French railways system is introduced and the interest in installing power electronic compensators in substations is highlighted.
Based on the step-down or step-up functioning mode of CCIs, two topologies of reactive power compensator are presented. Means for temperaturabhaengigen electronic power control of fan motors for alternating current, in particular for heating monophsae air conditioning.
