EL Inverter LTSpice model

I'm curious as to what a good way to model an EL inverter in LTSpice would be, so I can experiment with some dimming circuits without blowing up the bricks on my bench (or taking an unpleasant low-current shock to the fingers by accident. Ouch.)

It takes in some voltage between 1-5 volts and spits out around 50-100V RMS, proportional to input and load dependent. It's probably some kind of self-oscillating push-pull driver plus step-up transformer in a resonant circuit internally, like a fluorescent lamp ballast.

At the very least it would be nice to model the "line regulation" and some kind of equivalent output impedance.

model a Royer inverter, ltspice should be able to handle that easily.

Hello there!

Am planning something very similar myself. Have gone the experimental way f irst and successfully found that those common sealed 5V (USB) Inverters sol d on Ebay or Amazon for EL Wire are successfully dimmable with constant pow er (PWM directly did result in flickering despite high PWM freuncy, but wit h a low-pass filter after the PWM-input, it did work).

However I would like set this up in LTspice too. Do you happen to have modeled something successfully in the meantime?

Huge thanks in advance :)
