VOLTAGE REGULATOR WITH CONTROLLED CURRENT BOOST

摘要

A voltage regulating system for AC generators including a three phase current boost and a voltage responsive control circuit having a full converter type output stage. The three phase boost circuit and the full converter output stage are connected in series with the field winding of the exciter. At high power output levels, the inverting capability of the full converter power stage is used to oppose the voltage generated by the current boost to prevent loss of control over the generator, by diverting excessive boost currents through a load means connected to the current boost circuit.
