Webinar - New technologies to improve the performance of your servo drive


September 15, 2017

Learn about designing compact servo drives for precise position and torque control. Precise control requires minimum motor phase current ripple and accurate current sensing for reduced rotor vibration. This webinar discuses a high efficiency GaN power stage which enables high frequency switching for low phase current ripple. A high accuracy reinforced isolated current sensing solution using shunt resistors and delta sigma modulators is also discussed, which enables high performance in a noisy, electrical environment. 

What the Attendee Will Learn
