Abstract: A system includes a first controller configured to transmit a synchronization signal to a second controller. The second controller is configured to produce a PWM signal. The system also includes a counter configured to provide a count for the second controller, where the second controller is configured to initiate rising edges and falling edges of the PWM signal based on the count from the counter. The second controller is also configured to measure an error between a time when the synchronization signal is received at the second controller and an expected time of receipt for the synchronization signal. The second controller is also configured to adjust a period of the counter based at least in part on the error.
