Here's how to reduce the effect of capacitor switching on your power system Last month's article discussed exactly what happens when electric utilities switch shunt capacitors: power system components ...

Restrikes or re-ignitions occur when the dielectric strength of the open gap, during contact parting, is not great enough to withstand the recovery voltage across the open gap. With a capacitive load, ...

An undervoltage or voltage sag is a disturbance that commonly occurs during electrical faults or when equipment is turning on. They are produced when large currents are being drawn on the system. On ...

Many power supplies use hold-up capacitors to keep enough energy at the full-wave or bridge rectifier output to supply a load when the rectified voltage drops and rises again at the next half-cycle of ...

What are output capacitors and how do they impact power supplies? Simulating a circuit to reduce the amount of capacitors in a supply. What is adaptive voltage positioning? A power supply’s output ...
