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.
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 ...
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 ...
