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 ...

Did you ever wonder how the mechanical voltage regulator — that big black box wired up to the generator on a car from the ’60s or before — worked? [Jonelsonster] has some ...

Fig 1. Placing this two-terminal circuit between a GFCI line-load terminal and ground creates an adjustable line-voltage limiter. Fig 2. With the trip point set at 133 V rms, the circuit draws less ...

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 ...

When Chevrolet introduced the redesigned Corvette in 1963 one of the new features was the Delcotron alternator that replaced the venerable generator. Dubbed the 10 DN, the externally regulated ...

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 ...
