I see a huge inductor coil on the output side of all the EL inverter I open which is connected between two mosfets (I hope its a half bridge). Do you know how it is connected to the transformer output?
Hi,
I need help in designing an EL inverter (12 V DC to 110V/ 800Hz AC). I am new to power electronics, so need a full guideline for designing one. I read lot of articles online, but very few related to EL inverters.
Hope you guys can help me on this :)
Thank you,
Senan
Brian,
I am using a DVM as you guessed. I don't have a CRO right now, lemme check the output with that.
As part of learning, may I know how you calculated the power delivered as 18W.
Thanks,
Senan
Thank you for the calculations. I have removed the LED and the 880 Ohm resistor. Still the output pins 10 and 11 shows voltage around 4.8V. It should be at least something more than 10V.
The Vdd range as per datasheet is 0.5 to 20V. So if I am supplying 12V Vdd my output should be at least more than 10V at the pins 10 and 11. Unfortunately its 4.8 V.
Hi Tony,
What I am asking is, what power the above circuit can deliver(10W, 20 W or whatever).
Also the output pin 10, 11 is giving only voltage less than 5 V. But I am giving a 12 V supply.
Re: 12 V DC to 115 V AC sine wave inverter
Thank you. But how will I know the power it can deliver, i.e if I want to connect a device which draws 20 W power from the supply. I would i calculate that.
Hi,
I am making a 12 V DC to 115 V AC sine wave inverter with the circuit attached. But I don't know how much power it can deliver. If it is a 10 W or 20 W or whatever the output power is. Can anyone help me with it and please suggest the components if I need to increase the output power...
