Hi all, sorry for wrong Task Explanation.
Here i try again to explain my Task.
i have PWM step with 50ns. PWM clock freq. = 25MHz
I have deadtime as input in Volts From 0,5v to 3,25v.
if input = 3,25v then PWM freq = 1 µs (microsec) = 24 (deadtime)
if input = 0,5v then PWM freq = 250ns (nanosec) = 2 (deadtime).
To makeup a meaningful question, you should mention the used hardware (e.g. microcontroller). At first sight 25 MHz clock won't give 50 ns rather than 40 ns delay/pwm step size.
One point clarified, the other (which processor?) still open. Programming depends on the answer.
I don't see how period or duty cycle should be related to dead time. The effective duty cycle may be varied, depending on how the pwm generator is programmed (-> open question).
