WebMeaning of duty cycle. What does duty cycle mean? Information and translations of duty cycle in the most comprehensive dictionary definitions resource on the web. WebI believe any measurable duty cycle variation will be attributed to external factors, such as dead time as a percent of frequency (measurable duty cycle loss right off the bat), gate drive delay, rise/fall times of whatever the load (MOSFET) is seen by OUTA, OUTB. Use an NPO CT capacitor and 1% or better RT capacitor and call is a loss of 1-2%.
