Hello,
I am trying to create a 4 hz square wave inverter (alternating current). It needs to be around 36 volts, and will only pass a few tens of mili-amps (20-100 max)
I would think there would be a H-Bridge inverter chip that could do this...perhaps driven by pwm using a tl494 or 555 or other similar timer. I know there are alot of monolithic chips out there that are for motor controllers and the such, but do not know if they would be suitable for such a purpose. Many of the ones I have come across are run by changing the duty cycle, which means I would have to create some cleaver circuit which would change the duty cycle 4 times a second in order to control the "inverter" frequency, or use a micro controller, which I would Really like to avoid.
Does anybody know of any such simple solutions?
