ABSTRACT:
An AC line transient suppressor includes a first metal oxide varistor connected between the "hot" and "neutral" lines of an AC power system. A first inductor is connected from the hot line to one terminal of a second metal oxide varistor, the other terminal of which is connected to the neutral line. A second inductor having approximately twice the value of the first one is connected from the junction between the first inductor and the second metal oxide varistor to a hot supply terminal to which equipment to be protected is connected. A silicon suppressor having a predetermined clamping voltage is coupled between the hot supply terminal and the neutral line conductor. The inductance of the first inductor has a value selected to divert approximately 95% of the transient surge current through the first metal oxide varistor. The second inductor diverts approximately 65% of the remaining surge current through the second metal oxide varistor, so that only approximately 2% of the total surge current flows through the silicon junction diode suppressor, allowing it to provide a low clamping voltage.
