WebThe basic buck converter consists of a controlled switch, a diode, capacitor and controlled driving circuitry. The switch controls the flow of input power into output by turning ON and OFF periodically. The time for which the switch is ON during the whole period is known as Duty cycle. The value of duty cycle D ranges between 0 and 1. WebThe boost converter output-input voltage relationship is proportional to the duty cycle in the sense that higher D will yield higher output voltages for a given input voltage. If the input voltage is V in and the output voltage is V out , V out/ V in = 1/(1- D ), where 0≤ D ≤ 100%.

WebThe Duty Cycle for Boost Regulator (CCM) formula is defined as the ratio of time a load or circuit is ON compared to the time the load or circuit is Off and is represented as D = Vo-Vi/Vo or Duty Cycle = Output voltage-Input voltage/Output voltage.
