windings to the dc distribution bus to
allow
current flow back when said switching means are
disabled;
rotor position resolving means positioned within
said switched reluctance machine
for monitoring the angular position of said
rotor, said resolving means generating a rotor
position control signal;
current sensing means positioned in proximity to
said phase windings for monitoring
current flowing in each of said phase windings,
said current sensing means generating phase
current sense signals;
voltage sensing means coupled to the dc distribution
bus for monitoring dc
voltage at a point of regulation, said dc
voltage sensing means generating a bus voltage
sense signal;
a controller having a plurality of control inputs
and outputs coupled to said inverter
for monitoring and controlling system
performance during the start mode and the
generate mode of system operation; and wherein
said controller monitors said rotor position control
signal and generates said
switching control signals to enable at least
said first and said second switching means for
each of said phase windings at a fixed angle
prior to alignment of said rotor pole with said
phase winding’s associated stator pole thereby
coupling said phase winding to the dc
distribution bus and allowing dc phase current
to flow from the dc distribution bus, through at
least said first switching means, said winding,
and at least said second switching means, said
controller further generating said switching
control signals to disable at least said first
and said second switching means at a fixed angle
after alignment of said rotor pole with said
phase winding’s associated stator pole, thereby
