This simplest electronic choke circuit can be built within 20-30 rupees, it can glow open tubelights too, no need of a new tubelight.
Working voltage: 170~300V for 220V tube, 80~140V for 110V tube.
You can use a tungsten bulb of 100Watt rating of 230V/110V as the series inductor, you can use existing choke, or use fan regulator coil, or even Soldering Iron coil(min 65W).
For the diodes, IN4007 has reverse voltage protection of 1000V, use this of good company(i.e, MIC, ST,BEL).
Using low cost diodes can blow the capacitors. For capacitors, use Keltron or any other good company. You can use 400V capacitor if you cannot find 800V one.
Electronic choke circuit part list
- Diode: IN4007(MIC) x4 4/-
- Capacitor: 2.2mfd/800V x2 20/-
- Neon lamp(optional)x1 4/-
TOTAL 24/- ~ 48/-
Not mentioning 100 Watt bulb or other tubelight choke, as we can get it in our house.
Note that you can use 450Volts capacitors if you can’t get 800V ones in shop.
i build this circuit but i got some problems capacitors r burns after 6 r 8 hours and power is taking large than ordinary 4ow power so is there any simple and power saving circuit available i will thankfull to u to post this circuit i once saw on tv someone made a circuit that run on diodes and no bulb or choke needed in in circuit please post me better circuit thank u
I fear there’s no such circuit which can run tubelight only with diodes and capacitors without choke.
arun, who told
first u try this circuit and write the judgement. i have experience with this. this is a simple circuit to generate 1000v potential between the two ends of the 40 w FL.
MURALI, U CHANGE THE ELECTROLYTIC CAPACITOR WITH POLITER CAPACITOR HAVING .448 mF 400V IT WILL DURABLE.
GIREESH
I want simple Electronic choke circuit without using choke or bulb.Only using diodes and capacitors.
Thanks
No one for cheap cost circuit
Can you provide a low cost choke circuit with diodes and capacitors but with good protection.
No,sorry
nothing
The setup is voltage doubler.
Yes, it is.
