Question A-004-002-010

Excessive rectifier peak current and abnormally high peak inverse voltages can be caused in a power supply by the filter forming a:

Correct Answer

series resonant circuit with the first choke and first capacitor

Explanation

If the first choke (L) and first filter capacitor (C) form a series resonant circuit near a ripple frequency harmonic, it can lead to large oscillating currents and voltages, stressing the rectifiers.
