  7. Closed: Re: A Powerful 30A DC Motor Driver using Power Mosfets [PWM Controlled, Half Bridge]

    Well, No. That is the feature of the function generator which does not go to 100%. actually 100% is not a PWM anymore, it is a flat DC line.
    Yes, the frequency can be increased but anyway it passed...
