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 ...

Some systems require a voltage limiter to protect the input circuit. Designers can connect diodes (Fig. 1) to V CC and Gnd to create a simple solution. This simplicity, however, comes at a ...

The LM4041 has been around for over 20 years. During those decades, while primarily marketed as a precision adjustable shunt regulator, this classic device also found its way into alternative ...

Nexans, Siemens and American Superconductor Corp. have successfully qualified a transmission voltage resistive fault current limiter (FCL) that uses high temperature superconductor (HTS) wire. Nexans, ...
