WebDuty Cycle of the Chopper: The ratio of ON time to total time is known as the duty cycle of a chopper. It is represented by the symbol. The sum of the ON and OFF times is the total time period. Duty Cycle is equal to T ON / ( T ON +T OFF) α = TON / (TON+ TOFF) The following duty cycle is presented assuming that (T ON + T OFF) = T. WebA chopper uses high speed to connect and disconnect from a source load. A fixed DC voltage is applied intermittently to the source load by continuously triggering the power switch ON/OFF. The period of time for which the power switch stays ON or OFF is referred to as the chopper’s ON and OFF state times, respectively. simplyhealth corporate dentalWebBy removing variations of the chopper frequency, or frequency jitter, only the commanded variations remain.
