It is just a concept which i want to understand, let us assume V1 supply and i can control it either using controller and apply pwm signal of the required duty, and L1 is a motor. My question is if i apply a pwm of duty 50% will i see a voltage of v1/2 on the motor and similarly based on the duty the corresponding voltages are applied? Am i correct? The second question what is the minimum frequency of the pwm, i assume that if the frequency is below some level the formula of v1/2 may not apply. Am i correct?
