So how many will get cooked? Or is that the secret ingredient.

We've been waiting for victims. Since you spoke up first, it's into the pot you go.

 

we can change the transistors and capacitors and replace them with higher values isn't it?

That is what the author says. The author knows nothing about electronics.

The circuit is very old and originally used germanium transistors. They were PNP which explains why the capacitor polarity is backwards. Germanium transistors didn't have the emitter-base avalanche breakdown problem that silicon transistors have.

For the 2N3055 transistors to conduct 10A so that the output is 100W, their base current needs to be more than 3.3A. Even then, their max saturation voltage loss is 3V. So many paralleled power transistors and driver transistors are needed, or Mosfets.

 

sir, pleases, send to me the simple diagram of inverter. thanks

Sir and if i can have the connection. thank

Replace the transistors with MOSFETs and use BJT totem pole stage to drive the MOSFETs.

thanks

 

me too....
i need simple diagram ups 3 phase.....
please sir..........

thx....

 

Holy cow, it's the thread that refuses to die!

"I need (a) simple diagram (for a) UPS (with) 3 phases"

Well, I'm afraid you won't get it, because there is no such thing as a simple 3-phase UPS - yet!

 

Request for a circut diagram of inverter with over load protection.I will be Thank full to all.

 

The very simple square-wave inverter uses a fuse for overload protection.
The circuit won't power many electronic products that expect a sine-wave, not a square-wave, so why bother to add an overload cutoff circuit?
