One of the most popular circuits for amplitude control in oscillators is the soft-limiter circuit (Figure 1a). When the output voltage, V OUT (t), is small, diodes D 1 and D 2 are off. Thus, all of ...

Most oscillator circuits include a nonlinear amplitude control that sustains oscillations at a desired amplitude with minimum output distortion. One approach uses the output sinusoid's amplitude to ...

This file type includes high-resolution graphics and schematics when applicable. Measuring the signals from extremely high-impedance sensors is a difficult task. Such sensors can have output ...

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 ...

For the first time, a superconducting current limiter based on YBCO strip conductors has now been installed at a power plant. At the Boxberg power plant of Vattenfall, the current limiter protects the ...
