TRIGGER MECHANISM FOR CURRENT ACQUISITION USED FOR MOTOR CONTROL APPLICATIONS

摘要

A trigger mechanism for starting current acquisition for motor control applications is disclosed. The present invention may generate an edge (ADC trigger) that can be used to start current acquisition by the ADC. The present invention may reduce the overhead involved in synchronizing the current acquisition with PWM generation and also minimize the wait period for software conversions to complete by replacing software-based timing with a hardware-based trigger mechanism.
