How do snubber circuits offer circuit protection in power electronics?

3 days ago | eeworldonline.com | Rakesh Kumar

Snubber circuits are commonly connected across semiconductor switches for protection. Common ways of protection include suppressing V-I spikes and ringing, complying with SOA, resonance suppression, and reducing switching loss. This FAQ will provide insights into each of these ways they are addressed. Snubber circuits come in various forms, the most common of which are shown in Figure 1.
Bias Tee: Understanding Its Function in RF Design

4 days ago | eeworldonline.com | Bill Schweber

A conceptually simple passive component is used to combine or split DC and RF signals; however, its implementation has many subtleties. The RF world, operating at hundreds of megahertz and into the gigahertz range, is known for having many unusual components. Some are unique to that higher-frequency world, while others appear at lower frequencies but with different component sizes and physical construction.

What’s the relationship between Ohm’s Law and quantum mechanics?

1 week ago | eeworldonline.com | Jeff Shepard

Ohm’s Law is the classical physics explanation of the linear relationship between voltage, current, and resistance in a conductor. Quantum mechanics provides insights into the mechanisms behind this behavior, explaining why Ohm’s Law still holds true even on very small scales where quantum effects are significant. Ohm’s law is a macroscopic view of classical physical relationships.
