Abstract
An improved overvoltage protection circuit interrupts a power transmission path in an open circuit mode responsive to an overrange input power potential, and is automatically reset to its quiescent operative condition when the overvoltage condition abates. In accordance with various aspects of the present invention, AC energy is coupled by the instant arrangement at a reduced level while the fault condition persists, such that the driven load is continuously energized.
