529 678 Sida 2 De olika funktionerna i Figur 1 och Figur 2 beskrivs nedan. 529 678 Page 2 The various functions in Figure 1 and Figure 2 are described below.
Figur 1 Utifrån en likströmskälla Vl kan med en Spänningsreglering nivån/ spänningen på pulsen till primärspolen Ll väljas mellan olika nivåer beroende på vilken effekt som önskas ut från sekundärspole L2. Ett exempel kan vara att växla från 12 Volt till, 8 Volt.. Tekniken för detta kan var en ”step down” krets eller rent av en enkel emitterfölj are med olika utspänning.Figure 1 Based on a direct current source V1, with a voltage control the level / voltage on the pulse to the primary coil L1 can be selected between different levels depending on which power is desired from the secondary coil L2. An example could be switching from 12 volts to .8 volts. The technology for this can be a "step down" circuit or even a simple emitter follower with different output voltages.
Primärspolen Ll matas med ström när mosfet Ml leder och lagrar då energi . Fasningen av den sekundära spolen och diod Dl är sådan att ingen ström leds över i sekundärspole L2.The primary coil L1 is supplied with current when the mosfet M1 conducts and then stores energy. The phasing of the secondary coil and diode D1 is such that no current is conducted into secondary coil L2.
Den totala tiden mellan då mosfet M1 börjar leda varje gång , den s.k cykeltiden är konstant.The total time between when the mosfet M1 begins to lead each time, the so-called cycle time is constant.
Däremot kan den ledande tiden av cykeltiden variera t.ex +- lO-20%.On the other hand, the leading time of the cycle time can vary, for example + + 10-20%.
För att reglera den ledande tiden av cykeltiden används en krets för Pulsbreddsmodulering med fast frekvens.To regulate the leading time of the cycle time, a pulse frequency modulation circuit with a fixed frequency is used.
Enligt Lenz lags byggs under den tid mosfet M1 leder en motemk upp i sekundärspole L2 som omedelbart växlar riktning när primär spole Ll inte längre matas med ström. Dioden Dl kan nu leda. Dvs en ström matas ut via D1 och ”glättas” med hjälp av kondensator C2. I min figur 1 till en elmagnet i en hydraulventil.According to Lenz's law, during the time the mosfet M1 is built, a motemk leads up into the secondary coil L2, which immediately changes direction when the primary coil L1 is no longer supplied with current. The diode D1 can now conduct. That is, a current is output via D1 and "smoothed" with the help of capacitor C2. In my figure 1 to an electric magnet in a hydraulic valve.
Utspänningen är beroende av förhållandet mellan antalet lindningsvarv på spole L1 i förhållande till antalet lindningsvarv på spole L2. Detta förhållande kan uttryckas som N.The output voltage depends on the ratio between the number of winding turns on coil L1 in relation to the number of winding turns on coil L2. This relationship can be expressed as N.
Förhållandet N kan vara sådant att växlas spänningen i min figur till primärspolen från en spänning till en annan kan förutom att effekten ändras en signal erhållas. I exemplet ovan från 12V till 8V kan ett till eller frånslag ske av elmagneten.The ratio N can be such that switching the voltage in min fi gur to the primary coil from one voltage to another can, in addition to changing the power, a signal is obtained. In the example above from 12V to 8V, the electromagnet can be switched on or off.
Med en avledning av spänning innan Dl och använda den spänningspulsens börjanögonblick som start av en ”är puls” vars längd jämförs med den avledda spänningspulsens längd kan en styrning ske.. Detta möjligörs via en felkorrigering av skillnaden mellan ”är puls” längd och ”bör puls” som är den avledda spänningspulsens längd. Längden på pulsen styrs av pulsbreddsmoduleringen. Det har skett en information över till sekundärspolen som är användbar. I min figur 1 är det en RC-Servomotor.With a derivation of voltage before D1 and using the initial moment of the voltage pulse as the start of a "is pulse" whose length is compared with the length of the derived voltage pulse, a control can take place. This is made possible via an error correction of the difference between "is pulse" length and "should pulse ”which is the length of the derived voltage pulse. The length of the pulse is controlled by the pulse width modulation. There has been information transferred to the secondary coil which is useful. In my figure 1 it is an RC Servomotor.
Nivåen på den avlänkade spänningspulsen behöver inte låsas till en lägre nivå än den lägsta som huvudpulsen.Det kan dock vara en fördel beroende på hur felkorrigeringen sker.The level of the deflected voltage pulse does not need to be locked to a lower level than the lowest as the main pulse. However, this can be an advantage depending on how the error correction takes place.
Figur 2 Spole 1 Lindningen är koncentriskt lindad med spolen/ringen i övrigt. Lindningen är placerad i spår i gaveln på spolen/ringen. Lindningarna är s.k ”split bobin”.Figure 2 Coil 1 The winding is concentrically wound with the rest of the coil / ring. The winding is placed in grooves in the end of the spool / ring. The windings are so-called "split bobbin".
Lindningarnas riktning och in- och ut- matning skall vara gjord enligt” punktkonventionen” dvs följande förlopp skall gälla för dem, se figur l. Varje ände på spolama Ll och L2 är markerade med en punkt , vilket beskriver hur lindningen skall fungera: Dessa punkt markerade lindningsändor skall ha positiv spänning i samma ögonblick.The direction of the windings and the input and output shall be made according to the "point convention", ie the following processes shall apply to them, see figure 1. Each end of the coils L1 and L2 is marked with a point, which describes how the winding should work: marked winding ends should have positive voltage at the same moment.
Spole 2 I detta fall är primärlindningen i spolen den övre halvan i figur 2 och koncentriskt placerad innanför den sekundära lindningen som är på den inre mantelytan av spolen/ringen nederst i Figur 2. ' r 529 678 Sida 3 Lindningarnas riktning och in- och ut- matning skall vara gjord enligt' punktkonventionen” dvs följande förlopp skall gälla för dem, se figur 1. Varje ände på spolama Ll och L2 är markerade med en punkt , vilket beskriver hur lindningen skall fungera: Dessa punkt markerade lindningsändor skall ha positiv spänning i samma ögonblick.Coil 2 In this case, the primary winding of the coil is the upper half of Figure 2 and concentrically located inside the secondary winding which is on the inner mantle surface of the coil / ring at the bottom of Figure 2. 'r 529 678 Page 3 The direction of the windings and in and out - the supply must be made in accordance with the 'point convention', ie the following processes must apply to them, see fi figure 1. Each end of the coils L1 and L2 is marked with a point, which describes how the winding should work: These point marked winding ends must have a positive voltage in the same moment.
