Duty Cycle Formula Elements

Variables
Duty Cycle
A Duty Cycle or power cycle is the fraction of one period in which a signal or system is active.
Symbol: d
Measurement: NAUnit: Unitless
Note: Value should be less than 1.
Chopper On Time
Chopper On Time refers to the time period for which chopper was in ON state.
Symbol: Ton
Measurement: TimeUnit: s
Note: Value should be greater than 0.
Chopping Period
The Chopping Period is defined as complete time cycle, comprising both the on-time and off-time of the chopper switch.
Symbol: T
Measurement: TimeUnit: s
Note: Value should be greater than 0.

How to Evaluate Duty Cycle?

Duty Cycle evaluator uses Duty Cycle = Chopper On Time/Chopping Period to evaluate the Duty Cycle, The Duty cycle formula is defined as the ratio of the ON time of chopper to the chopping period(total time). Duty Cycle is denoted by d symbol.
