YUEQING, ZHEJIANG, CHINA, January 8, 2026 /EINPresswire.com/ -- As global energy systems transition towards digitalized ...

Guitar amplifiers using output devices such as the TDA7293 (100 W) or LM3886 (68 W) are surprisingly often damaged as a result of excessive supply voltage in the quiescent state. The transformers are ...

An additional circuit connected between the load side of a ground-fault circuit interrupter (GFCI) and ground provides overvoltage protection against long-duration overvoltages, e.g., where the line ...

A Zener diode is the simplest known type of voltage limiter (Figure 1) As soon as the voltage exceeds the rated voltage of the Zener diode, a current can flow through the diode to limit the voltage.

Among regulators, the simplest regulator circuit is for a low-dropout (LDO) voltage regulator whose topology is shown in Fig. 1. As a linear voltage regulator, its ...

American Superconductor Corporation and Siemens AG announced commercial-grade performance levels for a medium voltage superconductor surge protection device known as a fault current limiter (FCL). The ...
