High-efficiency, color-tunable AC/DC organic light-emitting diodes (OLEDs) have been fabricated by researchers in Germany and the UK. This development makes OLEDs even more attractive for lighting ...

The switching thresholds of the AC comparators U1.1 and U1.2 can be smoothly adjusted by the dual potentiometer R5.1, R5.2, Figure 1, and the potentiometer R8, Figure 2, from 0 to ±10 V. Figure 2 A ...

A superconducting diode bridge composed of four superconducting diodes efficiently converts AC to DC at cryogenic temperatures, achieving rectification efficiencies up to 42% ± 5%.

You can’t send the diode a signal and have it switch polarity or whatever. ... Just using diodes for all the switching, using AC for power, and switching the bias to control it as you mention.

The net result is that, in nulling A2’s output, A3 implicitly calculates a drive signal for O3/O4 that accurately and linearly mirrors the current sense signal at O1/O2. This signal is scaled by A4 to ...

But with forward bias (positive voltage to N-type and negative to P-type), the barrier lowers, allowing current flow, conducting during the positive half of the AC signal. Reverse bias (negative ...

[Doug] pulls a signal from the 9V AC power before it hits the bridge rectifier, using a 100K resistor and a zener diode to protect the microcontroller pin.

PLANO, Texas--(BUSINESS WIRE)--Diodes Incorporated (Diodes) (Nasdaq: DIOD) today announces the introduction of the PI5USB212, a USB 2.0 signal conditioner that operates from a supply voltage down ...
