Hi there,
I'm looking for a circuit design to convert 12V DC into 12V AC, at 50Hz or 60Hz. This is to control a solenoid rated at 12V 50Hz AC, and 8W. As it turns out, the solenoids I plan to use are rated for a higher pressure under 12 AC control than 12 DC, so that's the reason for going this way. I'm not sure I really understand why that's so, but it's what the specs say... A step-down transformer isn't an option, as it will be running in a car. :wink:
Anyways, I've spied a few 12V DC to 110/240 AC circuits, and was wondering if these are usable in modified form? Is it just a matter of dumping the transformer, tweaking the values, and going for it? Eg, **broken link removed**
Also, can anyone think of a sensible way to implement PWM control for this thing? I understand how that works with DC, but in this context AC PWM confuses me.
Thanks,
Ric.
