Post Testing Inverter Reply with quote
Hi all,

Just woundering if anyone knows of a design to test an inverter to make sure its working

a friend told me to use 3 x 3900 ohms resistors to lower the voltage for the led, would this be ok?

Thanks in advance everyone

Rik.

How about letting us know more about inverter first?

Is this CMOS inverter, DC/DC inverter, DC/AC?

What voltage?

That would be a good idea, forgot, accept my apologes

The inverter is designed to run small tfts, its run from the main battery of the laptop, have been told the voltage is around 600 to 1200 volts at about 1 amp


hope this helps

That means your inverted is 600-1000W, a kilowatt of power
for your lcd display? Must be very big.

P=U*I (1000V*1A=1KW)

The whole LCD monitor uses less than 200W, something is wrong here.
Get your numbers right and than we may be able to help you.
I doubt the backlight uses more than 30W or so and you're quoting
1000W.

When you go to the doctor you need to tell him where exactly it
hurts. You can't say: It might be my head, or perhaps my leg, hmm,
no, no, its my butt.
