I am trying to control a steady DC output voltage using a Micro controller with a PWM duty cycle. With the current schematic, the Voltage on
Vout is pulsing along with the Mosfet at what ever the duty cycle is. I know that this is the result of
Load being grounded only when Mosfet is "on", but can not figure out how to get around this. I want a smooth, controllable
Vout that uses the same
ground as the Fet. I know this is a noob question but any help will be appreciated. Also, I don't want to be picky but for me pictures really do speak a thousand words.
What I'm really looking for is a way to use a low-pass filter to smooth a PWM voltage. This smoothed out voltage will then be used to power a 1 ohm load. I know how to create a PWM voltage and a low pass filter, but not how to implement both to power something. Since I'm new to circuits, a simple schematic drawing will be very helpful.
