General Analog Thermometer Circuit

Published:2011/5/12 8:07:00 Author:Robert | Keyword: Analog, Thermometer

The analog thermometer circuit composed of HST1 is shown in the picture below. The HTS1 outputs current signal from its 2 foot and this foot is a high-impedance output port; but the voltage signal should output from the 3 foot and this foot is a low-impedance output port. It can use R2 to transform the current signal outputed by the sensor to be voltage signal U0, and then uses the 1.0 level 5V DC voltmeter to display the measured temperature value. When taking R2=10kΩ, the voltage temperature coefficient is 10mV/°C, the output impedance would be less than 100Ω. Just this case the output voltage-temperature (U0-T) feature curve is shown in the picture below.   (View)

Heteropolarity Turn-Off Absorption Circuit

Published:2011/5/5 1:39:00 Author:Robert | Keyword: Heteropolarity, Turn-Off, Absorption

The picture 1 shows the heteropolarity turn-off absorption circuit which has a capacitor in parallel with the switch. When the switch is conducted, the capacitor Cv discharges quickly through the switch V, which makes the switch's additional current large during the conducting moment, and this could damage the switch. To avoid this situation, the pratical shutdown absorption circuitis RCD networks. It is called heteropolarity turn-Off absorption circuit because there are diodes in it. The picture 2 shows the polarized snubber circuit -- application of RCD networks in buck converter, and it is in parallel with the switch. The compositionof the RCDis using a resistance Rv in parallel with a diode Dv, then take them in series with a capacitor Cv. The Rv's function is limit the Cv's discharging current when the swith is conducted, and also it transfers the energy in Cv to the resistance Rv to be consumed away. The diode Dv's function is making Cv be charged through the diode Dv when the switch is closed, and also the Rv coube be shorted by Dv.   (View)

Pincushion Correction Circuit-Discrete Circuit Diagram

Published:2011/5/4 8:17:00 Author:Robert | Keyword: Pincushion Correction, Discrete

It is the parabolic wave signal addedon the r520, and the user can adjust the parabolic wave signal amplitude by adjusting the r520, which canadjust the pincushion correction value as well. It is DC voltage added on the r523, and the user can adjust the line width by adjusting r523. This second circuit extracted from the Venus d2918 type pincushion correction circuit, whichhasjust V951 and v950 two-stage amplification more than the firstpincushion correction circuit shown below. The reason is that the field sawtooth wave is not taken from field deflection coilssampling resistor, but from tda8838's 46 foot, so thatit'sadded a two-stage amplification due to its small magnitude. The models which use this pincushion correction circuit have: Korea Samsung mc-15 module, Venus c6418, v6458, Peony 64c1, Lehua ct6388w and so on. The field sawtooth wave voltage is send to the pincushion correction circuit from the p404's 4 foot, and the r455, c454, r457 make up the integral circuit to integrate the field swatooth wave and produce the up-convexparabolic wave voltage. This voltage then is added on the b polar of the parabolic wave shaping and amplifying tube. Afteramplifying and shaping the c polar output 9V (peak-peak value) down-convex parabolic wave voltage. Then after the level width adjustment, left-rightpincushion distortion adjustment network made up by the vr451, vr452, r464, r463, r462, this voltage wave is added to the polar of the compound tube made up by q453 and q452. After amplifying the q452's c polar outputs 12.5V (peak-peak value) parabolic wave voltage. At last this voltage wave is send to the line scan circuit from fr459 and p403's 3 foot to modulate the line scan current. So this process achieve the goal of pincushion distortioncorrection. The vr451 is theline width adjustment potentiometer, thevr452 is pincushion distortion correction potentiometer.   (View)
