Troubleshooting refrigeration equipment often requires measuring various electrical properties such as voltages, current flows, and resistances. Understanding these basic electrical fundamentals and ...

Part 1 of this series focuses on high-performance electronic loads for testing power supplies that have low output voltage and high current. It describes the necessity for special electronic loads, ...

Current transformers or CTs are indispensable anywhere high currents are measured and processed. These instrument transformers effectively diminish high-voltage current flows for a convenient way to ...

One of the most important electrical terms to know is AC. Ever since the Tesla-Westinghouse power plant at Niagara Falls came ...

Power supply manufacturers sometimes hear from customers with unfortunate dilemmas, such as, “I need to operate the power supply outside its rated voltage range.” Or, “What happens if I exceed my ...

GaN devices have low gate-charge requirements, low gate voltage margin, and packages that are designed to expose as little ...

The power transistor must be chosen to provide fast response while also withstanding high power dissipation. Several electrical and thermal characteristics must be considered: 1. An array of N current ...
