Claim:
1. An electrical power system overvoltage protection arrangement, comprising: an overvoltage protection device having a fail-shorted surge protection device; and a variable frequency generator that provides a first percentage of total AC power to an AC power system, and a second percentage of total AC power output through a DC bus to the fail-shorted surge protection device of the overvoltage protection device when the fail-shorted surge protection device is activated, wherein the overvoltage protection device is configured to activate the fail-shorted surge protection device if a voltage of the power being provided to the AC power system exceeds a threshold value, the fail-shorted surge protection device configured to absorb the second percentage of the total AC power in excess of the threshold value to protect the AC power system from an overvoltage condition, wherein the overvoltage protection device includes:
