Testing high power, high brightness light-emitting diode (HBLED) modules is increasingly challenging. One crucial characterization function is the ability to detect which modules are affected by the ...
The circuit in the diagram is a very handy tool for rapidly checking all kinds of thyristor (SCR, triac, …). In case of a triac, all four quadrants are tested, which is done with S3, while in case of ...
Precision temperature control circuits for small thermal loads like oscillator crystals and voltage references tend to be fairly easy to design. This is because simple, well-behaved, linear-output ...
