Using the fast dynamic load described in this Design Idea to test the transient response of a power system can reveal many critical operating characteristics. The voltage deviation resulting from a ...

Modern power systems face increasing challenges as they integrate renewable energy sources and advanced digital technologies. Key to maintaining reliable electricity supply is the design of robust ...

Regardless of the system architecture, the circuit design, or the power levels involved, transient load current step testing is a critical aspect of power-system design, test, and verification.

Under given scenario, accident type, and clearance time, calculate the first critical point and obtain the initial operating area. Then space division method is promoted to compress search space for ...

Find a downloadable version of this story in pdf format at the end of the story. Processor-based systems place strenuous voltage regulation requirements on their power supply. In many instances, this ...

The programmable logic controller (PLC) is an important component in most modern automation and process control systems today. It's also susceptible to lightning-induced transients. To verify the ...

Second-stage output filters are often used to attenuate the output voltage ripple of a switching power supply. They can also isolate one load circuit from another. In this power tip, I will describe ...

For years, transients generated on the utility grid have plagued industrial and commercial facilities with a high concentration of variable-speed drives (VSDs) and other sensitive loads. The common ...
