I'm working on a project in which I'm hoping to integrate several small segments of pdlc film, which starts off diffuse white/'frosted', turns clear when excited with 110V AC at 50Hz and is apparently dimmable although I haven't tried that yet. This is the closest thing I have to a datasheet:
I want to power 6 segments of film from a 1s lipo cell, which is already boosted to 5vdc for other parts of the project. In total I will be using 13sq.cm at most so they won't draw more than 1.5mA. I also need to figure out how to control the degree of transparency of each segment independently, preferably using PWM signals from an arduino.
Size is critical as everything needs to fit inside a handheld toy and it is already crowded!
Would it be feasible to create an AC signal using arduino PWM output and boost that to the required voltage?
All of the solutions I can find off-the-shelf for boosting the voltage are just too big for my project but also provide way more power than I need. Most of their bulk is transformer and heatsink. Is their a way to get the voltage gain at 50Hz without a (relatively speaking) bulky transformer? All of the smallest transformers I can find have a minimum frequency way above 50Hz.
