The air compressor is essential to the proper operation of subway cars that use an air brake system [1 ... This is a standard current limiter circuit [2] [3]. The transistor that failed the most was ...

For standard fuses, the major detraction is their one-time use. An alternative is the ... Another hot-swap circuit (top) implements current sensing and 2A-limiting with a pnp transistor, as ...

On the one hand, using a high-value ... a transistor and resistor to the open-circuit drive overcomes this dilemma by limiting current through the drive transistor. Transistor Q2 provides the ...

The current limiting circuit, though, is where things get interesting. Rather than use an op-amp, [DiodeGoneWild] chose a simple discrete transistor current-sense circuit. To make it less ...

To demonstrate the simplicity of such a component, [Eric] constructs a current limiting circuit using a JFET and feedback potentiometer then confirms the functionality on a curve tracer.

Point out that most electronic devices run on a small current that is amplified. You’re going to build two simple transistor circuits, each using a single transistor. These circuits will allow ...

Adding a clamp circuit to the well known current-limiter protects the "pass" transistor from over-currents ... the results from a test circuit built using the resistor values quoted above, with ...

Transistors are an indispensable building ... Swedish Foundation for Strategic Research to develop new wireless circuits using nanotechnology. The newly developed transistor technology will ...
