ATTENTION : REQUIRES TUNING !!! [ NOTE 2015 ] Better with a Toroidal(round,circular)-Transformer 12V (2x12V). PS: An (quality)upgrade at:* Kywdo111 *(YouTube channel), and more explanations. (The transistors remains COLD !!! - at that consumption WITHOUT heat-sinks ! ). (Works also with a 220V or 120V Transformer) PS : New Bias-type, very stable !!! ................................................ Dictionary : *An INVERTER : from DC to AC . *A TRANSFORMER : from AC to AC . ................................................................ NOTE ( !!! May 2015 !!! ) : [ With Tr.:2x12V(5A)/230V, and 3W-LEDs-bulb like load, and 12V/9Ah Battery (source) ] Ab.*** 53Hz *** , on my USB-Oscilloscope, ... I'll try to see the frequency on an other Oscilloscope ( maybe at a work-shop ).

Sir, how do I do this inverter for 110 volts? The two 400 volts capacitors and the two 2.2 k need to be changed for a 110 volts inverter? Thank you!
Luis M. Peña (3 years ago)
Good. thank you.

Use a 120 volt transformer instead of a 240 volt one.

Where is is connected the negative battery?

+Son0rOo it's above the lower 560ohm resistor betwen the two transistors

if you want to replace 2N3055 with the d718 how to?
Tiago NET (3 years ago)
look the current!!! 2N3055 is 15A complementary NPN, 60V, 115W. Verify the datasheet the D718!!!

sure there is a pause when playing but can you at least give us 1 or 2 seconds to read your post be for you change the text .

what's the output frequency ?
Tonny Cassidy (3 years ago)
how about the waveform ? pure sine,modified sine,square ?

it work with neon sign? ? and neon bulbs?
