Multiphase buck topology is preferred for processors that are drawing increasing amounts of current at lower voltage. Common design practices limit the open-loop bandwidth of the control system to 10% ...

A new software product promises to boost the bandwidth of a servo drive’s current control loop, opening up new possibilities in industrial motion control applications. Fast Current Loop software is ...

It’s normal to assume that there’s an easy way to relate the bandwidth of a power-supply control loop to its transient response—no good reference exists that defines this in simple terms. It seems ...

The Kollmorgen S200 series servo drives are all-digital industrial drives with a velocity loop bandwidth up to 800 Hz. High resolution, 24-bit feedback and high performance 3-5 kHz current loop ...
