    Please help me understand how pulse width modulation switches operate. I understand that a signal is sent to a device and measured in frequency percentage. Where do I go to learn more about how and why?

    There are many many articles out there on the Internet on this very interesting topic. Just google "pulse-width modulation". Here is just one of those articles. It introduces the topic at the basic beginner's level. You should be able to get a good feel for PWM technique and then you will be able to expand on that knowledge.
