The days when converter manufacturers would have little option but to rely on the expertise of power-module specialists to design filters, optimize the control loop, and provide the result, have given ...

Due to their versatility, ease of design, and low cost, flyback converters have become one of the most widely used topologies in power electronics. Its structure derives from one of the three basic ...

Network analysis is a powerful and well-established method of characterizing and optimizing a control system. [1] Unfortunately, making a successful measurement can be difficult and frustrating ...

H-bridge buck-boost ICs are widely used in applications requiring a constant voltage or current source even when the system ...

A Protection and Control (P&C) design package for a typical substation includes a number of interrelated drawings, including one-line diagrams, schematic diagrams, wiring diagrams and interconnection ...

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 ...

Controlling hydraulic motion with precision involves understanding the fundamental difference between servo motors and hydraulic actuators. Electric motors generally respond linearly to control inputs ...

Step motor control offers a powerful alternative in the right applications. Step motors are popular first and foremost because they are easy to use. They do not require an encoder to maintain their ...

The goal of controlling a system is to reach or retain stability. In control theory, stability is described with the Lyapunov stability criteria and mathematical models that set into relation the ...
