The Laureate duty cycle transmitter tracks ON or OFF period as a percentage from 0% to 100% of total period of repetitive pulse trains. In the illustration, duty cycle is 100 x t/P. The trans-mitter determines duty cycle by averaging an integral number of periods over a gate time, ...

A motor controller for a direct current motor includes a first node receiving first PWM signals having a duty cycle indicative of a desired rotational speed of said motor and an input node receiving second digital signals, the frequency of said second signals indicative of the rotational speed of...
Duty cycle (or duty factor) is a measure of the fraction of the time a radar is transmitting. It is important because it relates to peak and average power in the determination of total energy output. This, in turn, ultimately effects the strength of the reflected signal as well as the ...

An asymmetrical duty-cycle DC-DC power converter was proposed recently, which allows zero-voltage switching while keeping the switch conduction losses as low as in standard hard switched PWM power converters. Further developments now allow the asymmetrical circuit to exhibit lower conduction losses than...
