Linear vs. Switch‑Mode Power Supplies: What’s the Difference?
Power supplies are the unsung heroes of all electronic systems, providing stable voltage and current to keep circuits running. Two of the most common types are linear power supplies (LPS) and switch‑mode power supplies (SMPS)—and though they serve the same purpose, they work in very different ways. A linear power supply converts AC to DC using a transformer, rectifier, and […]
How a Metal Oxide Varistor (MOV) Protects Your Circuit
A Metal Oxide Varistor (MOV) is a key component in surge protection. It’s designed to guard sensitive electronic circuits against sudden voltage spikes—like those caused by lightning strikes or power line surges. An MOV is made from a blend of zinc oxide particles sandwiched between two metal plates. Under normal conditions, it acts as an insulator, allowing almost […]
