Sine Wave "Generator" to drive Electroluminescent

[BOXBOX]

Hi there..

I am currently working on a project, to design a Electronic Driver for Electroluminescent (EL) Lamp.

The EL Lamp needs to be driven by a sine waveform of 135Vrms (approx 200Vpeak) @ a frequency of 1300Hz. On the whole, the driver itself, should be powered by DC supply (Batteries).

So far, i've looked into PWM & buck boost circuit, but don't seems to be getting the desired results.

So i hope to seek advices & comments from u guys here at EDA Board..

Hope to hear from u guys soon..

Thank you & regards..

There's probably half-dozen different driver designs. What application is the lamp used for?
How are your priorities split between:
- heat dissipation in the driver
- battery life
- Electro-magnetic interference (EMI)
?

hi kender..

Thank you for your reply..

The application of the EL Lamp is for leisure or signage use. Coz the EL Lamp will be very flexible, it'll be one of those u see ppl wearing them on clothings?

Size & cost of the driver would be a priority in the driver design..

Size & cost of the driver would be a priority in the driver design..

Here's a datasheet on a small single-chip EL lamp driver: https://www.onsemi.com/pub/Collateral/MC33441-D.PDF

thank u for the recomendation kender..

i've looked thru' the data sheet..
Think i did not mentioned that the output from the driver should be a sine waveform of 135Vrms (approx 200Vpeak or 400Vp~p) @ a frequency of 1300Hz.

The MC33441 chip is only capable of supplying approximately 140Vp~p.

hi there..

if i hve a output voltage of 184Vp~p, anyway i can amplify it to about 400Vp~p instead?

pls advice.

Thank you..
