Duty Cycle (D)

The ratio of the ON time (

T_{on}

) to the total switching period (

T_s

). It governs the average output voltage (

V_{out} \text{ or } V_{avg}

) in many converters:

V_{out} \approx D \cdot V_{in}

📜

The statement of the theorem

Let

T_s

be the total switching period and

T_{on}

be the duration during which the switch is ON. The duty cycle

D

is defined as the dimensionless ratio:\n

D = \frac{T_{on}}{T_s} \text{ such that } 0 \text{ and } D \text{ are constrained by } 0 \text{ and } 1
