For the first time, researchers in China have demonstrated a high-temperature superconducting diode effect, which allows a ...

Snubbers play an important role in switch-mode power supplies. To understand use of the snubber, we have to look at the performance of a switch-mode power supply. Fig. 1. RCD and R2CD snubbers for ON ...

The circuit was designed to provide a means for measuring the operating voltage of zener diodes before applying on a circuit. Zener Diode – a special kind of diode that permits the flow of current in ...

The more common approach to manipulate the incoming AC wave so that both halves are used to cause output current to flow in the same direction is the use of full-wave rectifiers. A full-wave rectifier ...

A merged-structure device combining pn junction and Schottky operating modes in one diode addresses design challenges in single-phase boost converters while reducing component and system costs.

A PQ expert can link an abnormal current or voltage waveform to an abnormal condition on a power system just as a handwriting expert matches a signature to a person. Many facilities now have online ...

A “loose neutral” in a residential location can cause equipment damage and even a house fire. An open neutral may start as a high-resistance connection that shows subtle signs in waveform capture data ...

Variable speed drives (VSDs), sometimes also known as variable frequency drives, are electronic devices used to regulate the speed of an ac induction motor. Electric motors consume approximately 25% ...
