i just wanna share my little project on 555 timer  lalo na sa mga naghahanap ng high voltage transformer

driver.  ;D

it operates on 12-30V. estimated output is 4 to 6kV gamit ko ung transformer sa powerpack ng photocopier iron core type

ginamit ko na lng ung clay to take the pics of the arc mahirap na mahawakan ung wire  ;D

gamit kong power transistor dito is MJE3055 NPN transistor pwede rin power MOSFETs heat sink is needed




heres the simulation in proteus ;)


the diagram  ;)


if any question just feel free to ask  ;D ;D ;D

yung IR2152/IR2153 *IR2153 nakabili ako sa newport ay pwede rin dito sa cicuit nito :D based din sya sa LM555 pero dalawa na yung output nya pangdrive ng transistor ;)

depende na un sa gagamit kung masyado siyang pabaya  ;D ;D

yup base sa datasheet nun mukang parehas nga sila ng 555 timer ung ckt sa taas pwede rin siya iconfigure as half bridge or H-bridge pero hindi ko pa nasusubukan. ung sa output nung ckt pwede mo gamitin lahat ng gates ng 74LS08  :D

Saan mo naman yan gagamitin sir TS, ako may ckt din ng HV nakatambak lang sa ngayon.

balak ko gumawa ng maliit na N2 TEA LASER pwede rin pang test ng diy HV caps  ;D

tested ko na sya sa high voltage h bridge 300VDC :D

ganun ba pero in comparison with IR2153 and my ckt above mas ok gamit ung IR2153 isang IC na lang kasi sya at designed sa to operate at higher voltage mostly for SMPS

diba parang driver din po yan ng mga bumbilya ng pang 12volts? gaya ng flourescent tube? ganda kc panuurin spark nyan e, yung sakin low voltage linagay ko sa loob ng bute, ganda ng spark sa loob, light blue din yun spark..

i suggest argon if you want high pressure arcing using hv/hf supplies.

^ i work with gtaw kaya may konting experience ako with argon.
at the same time malalaki ang plasma globes 3" to 2' Dia. kaya argon ang nilalagay na gas sa loob.
if low pressure or vacuum ang sa loob nang plasma globe. it poses a danger of implosion. parang CRT tubes.

back to argon. if you want ambient/high pressure arcs get argon.

speaking of gases and HV arcs pwede mo subukan ung iba't ibang type ng noble gase for colored arc  ;D like ung argon kasi gamit as shielding gas for gtaw pwede rin for normal pressure confined sa loob ng globe

about naman ung low pressure hindi naman kelangan na sobrang baba or near vacuum ung pressure ung tama lang na magkakaroon ng arc discharge sa loob i consider na rin natin ung gagamiting glass globe  ;D

Pwede kayang gamitin as crt rejuvinator yan o dapat mas mababa konti ang hi-vo?

Sir, ask lang ako...is it dangerous ba?kc 4kV-6kV nya...naka2patay ba yan?la lang...ilan ung output current nyan sir?
tnx...

medyo delikado lalo na accidentally na nahawkan mo ung both terminal with both hands hakit ung isang terminal mararamdaman mo na ung daloy nang kurente sa tingin ko may may posibility na makamatay kung hahawakan ng matagal sa magkabilang terminal idagdag mo pa kung yung hahawak ay may sakit sa puso

regarding sa current nsa 5-6 micro amp ata lang ung output base na rin sa pinanggalingan ng trasnformer ;D
