Simple 12V Inverter for Fluorescent Lamp

This 12V inverter is very easy to construct, reliable, and even powerful enough to light up a 15W fluorescent tube (if you’re cool your transistor well). The only hard-to-find piece of this baby is the so-called yellow inverter transformer. It’s a miniature high-frequency transformer that has a 25mm x 20mm x 5mm ferrite core, 30 turns of primary, 15 turns of feedback, and 250 turns of secondary all concentric, wound on plastic frame than wrapped with a ‘yellow’ adhesive tape.
If you can’t find it in your local electronic shops then search for old portable rechargeable fluorescent lanterns, since they have at least one yellow inverter. Of course, you can wind a handmade transformer which would do the same, but it is a very difficult task when you don’t have an original to inspire and it will still need an appropriate ferrite core.

12V Inverter for Fluorescent Lamp Circuit Diagram

This 12V inverter is a single transistor oscillator circuit. Current passed through primary winding inducts a magnetic field to the core and the core gives the energy back to the feedback winding with a delay determined by the core material and windings. System then oscillates continuously on a frequency depending on this timing. You cannot use 2SD882 with voltages over 4.5 volts. It is only needed if you are going to feed the circuit with only 4.5 volts. Equivalent transistors may not work as good as 2SD882 (NEC Electronics, Japan).

12V Inverter Characteristics
Bipolar NPN transistor: 2SD882 (or D882 as labeled)
Casing: TO126
Max. Collector current: 3 Amperes
Max. Total power: 10 Watts, while a case is at 25 degrees Celsius.
Transition frequency: 45 MHz
Max. Collector capacity: 45 pF
hFE (current gain) : 160 at 1 Ampere (typical value)
Bipolar NPN transistor: BD243C
Casing: TO220
Max. Collector current: 6 Amperes
Max. Total power: 65 Watts, while a case is at 25 degrees Celsius.
Transition frequency: three MHz
hFE (current gain) : 30 at 300mA (minimum value)
In case you decided to build your own transformer for the 12V inverter, here are the instructions to create one:

12V Inverter Fluorescent Lamp Transformer

First of all, you have to find a ferrite core transformer frame. It may be found in discarded rechargeable fluorescent lanterns (in this case it will be probably ready to use), fluorescent tube lights build to use in cars, at electronics stores, and in the energy saver lamps.

12V Inverter Fluorescent Lamp PCB Layout

Although the 12V inverter circuit has got a few parts, you may want to create a PCB to fit components on, after a successful test run. Here is a 12 inverter PCB suggested, easy to create and small enough to place almost anywhere. You may refer to my PCB design page to get info on how to create your own PCBs.

Rangkaian Lampu TL Menggunakan Aki 12V

Posted by e2ndycom on 26 November 2011

Posted in: Elektronik Service.

Rangkaian ini menggunakan Transistor 2N3055 dan beberapa rangkaian passip lainnya,jika di perhatikan sekilas rangkaian ini cukup sederhana, tetapi saat anda mencoba merakitnya mungkin anda akan mengalami kesulitan dalam pengadaan trafonya. inti trafo bisa menggunakan batang ferit yang dililit menggunakan kawat email tembaga berdiameter 0,1 mm pada sisi skunder (yang ke lampu TL) dan 0,8 mm pada sis primer. Selamat mencoba.

notes:

• L1,L2 = 30 Lilit/0.8mm
• L3 = 600 lilit/0.1mm
• perhatikan arah lilitan titik A dan B harus saling membelakangi

Acer Aspire one kav60, wlan, lan driver untuk windows xp. atheros ar5007eg.

Sobat saya berbagi file nih, driver wifi, lan, wlan untuk acer kav60 yang dari atheros. moga berguna untuk teman-teman yang suk otak atik komputer, atau yang drivernya hilang.

ntar ya biar diaupload dulu
