The circuit in Figure 1 provides a low-cost, isolated ac-line monitor that measures ac-line-voltage level and has some other unique capabilities. The analysis of the circuit is straightforward: When ...

Editor's Note: Here's another take on the transformerless AC line power supply, which finds use in some well-insulated, low-power devices. Our technical reviewer pointed out that C ac should be an ...

Advancements in power TVS diodes have made them an effective alternative to metal oxide varistors (MOVs) in protecting AC and DC power supplies from power line surges and indirect lightning strikes.

Bourns, Inc. announced the introduction of new high Power TVS diode models in SMD packaging for use in AC and DC power line applications. The new models feature high current bidirectional port ...

Designing automotive electronics presents numerous technical challenges, including the need to protect against electrical hazards under the hood and in the cabin. The three major sources of electrical ...

[Hales] has been on a mission for a while to make his own diodes and put them to use and now he’s succeeded with diodes made of sodium bicarbonate and water, aluminum tape and soldered copper. By ...
