Abstract
This paper describes a detailed analysis, verified
by practical experimental results, of a synchronous
reluctance machine with two similar stator windings and
capacitance injection using a static switch. The steady state
equivalent circuit is developed and used to investigate
leading capacitance injection into the machine via a
balanced three phase auxiliary winding that is only
magnetically coupled to the main winding. The scheme was
found to improve the torque and power factor performance
of the machine as well as reduce harmonics in the line
current. Two switching topologies were utilized for the
static control in this arrangement, and both were found to
present good and comparable results. Experimental results
corroborate the simulations.
