WebThe differences between these two can be discussed below. Time Ratio Control. In the time ratio control the value of the duty ratio, K =TON /T is changed. Here ‘K’ is called the duty cycle. There are two ways to achieve the time ration control, namely variable frequency and constant frequency operation. WebPulse skew (tsk(p)) is the magnitude of the time difference between the high-to-low (tPHL)andthe low-to-high (tPLH) propagation delays when a single switching input causes one or more outputs to switch, tsk(p) =tPHL −tPLH . Pulse skew is sometimes referred to as pulse width distortion or duty cycle skew. INPUT OUTPUT 1 OUTPUT 2 OUTPUT n ...
