ALLOWING IMMEDIATE UPDATE OF PULSE WIDTH MODULATION VALUES |
摘要 |
A pulse width modulation (PWM) generator having asynchronous updating of its PWM duty cycle and/or period values allows immediate correction for the new PWM duty cycle and/or period values instead of waiting until the end of a PWM period to accept the new duty cycle and/or period values. This reduces the latency in a control loop when responding to changing system status, e.g., changes in PWM duty cycle. Also the PWM duty cycle is prevented from "running away" (e.g., missing a PWM cycle) if the PWM duty cycle timer/counter has advanced beyond an updated duty-cycle maximum value. |
