Abstract
A current controlled shunt regulator uses logical OR gates and comparators corresponding to each field effect transistor (FET) shunt to redirect power to a neutral line whenever a controller indicates that power should be redirected, or whenever a phase voltage connected to the FET shunt is negative. The logical OR gate accepts inputs from the comparator and from the controller and outputs a control signal based on these inputs. When power is not being redirected by the FET shunts, AC power from a permanent magnet alternator is allowed to flow unimpeded to a DC rectifier which converts the power to a different format.
