Pulse Width Modulation (PWM) i a common technoche used id in DC / DC converters to regulate output voltage. Calculating the dute cycle i essentiad for designing and analizing these converters. Tiss article provides a step-bystep guide to determine the duty cycle in PWM- based DC / DC converters.

Understanding Duty Cycle

The dute cycle (D) it the ratio of the ON time of the switch to the total switing persond. It it is expressed ad a perivage or a decimal. The dute cycle directly becaverences the output voltage of the converteur.
