Steve Sandler explains what every engineer should know about ‘non-invasive’ stability assessments. The non-invasive stability assessment is a method that uses an output impedance measurement to ...

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 ...

Amathematical model is always helpful in determining the optimal compensation components for a particular design. However, compensating the loop of a WLED current-regulating boost converter is a bit ...

For the PDF version of this article, click here. More than 80% of the motors bought each year continue to be low-cost single-phase ac motors. Because these motors are not very efficient when ...

Good building mechanical design requires a firm grasp of the mechanical engineering fundamentals (thermodynamics, psychrometrics, the fan laws, etc.). The same can be said about the BAS design needed ...

Step motors are popular first and foremost because they are easy to use. They do not require an encoder to maintain their position, and unlike DC brush or brushless DC motors when used for positioning ...

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

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 ...
