Abstract:
In a voltage regulator for limiting the output voltage of an alternator, a control circuit comprising:(1) a full wave rectifier for impressing a series of half wave pulses onto a first circuit in correspondence with the output of said alternator;(2) a switch having a gate, an anode connected to said first circuit, and a cathode connected to a second circuit;(3) a gate control connected to said first circuit and arranged to generate an output signal when said half wave pulses produce a sufficiently high input voltage to said gate control, and impresses said output signal onto a gate circuit connected to said gate of said switch for rendering said switch conductive;(4) a detector connected to said second circuit for impressing a clamping signal onto a third circuit upon detection of a specific voltage level on said second circuit; and(5) a drain connected to said gate circuit and said third circuit for interconnecting said gate circuit to ground only when said clamping signal is on said third circuit.
