2. Are all CCFL inverters short circuit current limited?

Thanks for the help!

To acheive this operation efficiently, the inverters are designed to have an open circuit voltage sufficient to "fire" the tube. Then, a series impedance, typically a small, high voltage capacitor, limits the operating current.

Since the capacitor is a reactive load (not a resistor), it doesn't consume much power in serving it's function, and the circuit remains efficient.

Hi hobbs,

What is the context of the question?

I am wanting to use a ccfl inverter for something other than a ccfl which has a constant resistance of about 50 ohms. I'm not sure if the ccfl inverter will work with such a low impedance load. I know the inverter puts out a higher voltage at first then it drops. I'm just not sure if the inverter will work when it starts out with a low impedance load?

What is the load? What voltage do you want to put across the load? Why do you want to use a CCFL inverter?I am wanting to use a ccfl inverter for something other than a ccfl which has a constant resistance of about 50 ohms.
