Single-phase and 3-phase AC squirrel cage induction motors need some type of control circuit to initiate a start or stop function. The two types of ladder control circuits commonly used are the 2-wire ...

If you have ever read advanced textbooks or papers about electronics, you may have been surprised to see the use of complex numbers used in the analysis of AC circuits. A complex number has two parts: ...

When you determine conductor sizes for low-voltage feeder or branch circuits, do you account for voltage drop? Some people believe this is unnecessary, and some believe that doing so is a Code ...

A phase vector or phasor in physics and engineering signifies a sine wave whose amplitude and frequency are time-variant. The behavior of a sinusoid is decomposed by phasors into three independent ...

When India’s first Prime Minister Jawaharlal Nehru visited the planned site of the Bhakra Nangal Dam in Bilaspur in 1954, he called dams “the temples of modern India”. Contained in his turn of phrase ...

The Type PFCH capacitor series from Cornell Dubilier Electronics, intended for the ac output of large inverter systems, filter undesirable harmonics before power is delivered to the grid or load. The ...

The increasing use of integrated circuits in modern electronic systems has resulted in a growing awareness about lightning overvoltage hazard. The integrated circuits, especially large-scale ...

A new IC-based approach to EMI filtering in ac-dc power subsystems dramatically cuts inductor size and offers other benefits as well. The nature of the EMI problem in ac-dc supplies and its ...
