Three-phase induction motors are the most popular motors
in electric drive applications since the edge of Tesla [ 1]-[3].
The three-phase induction motors are more efficient, less cost,
last longer and have better torque/speed characteristic than
single-phase motors. However, the three-phase public network
is often not available, especially in some areas where it may
not be economical to install three-phase distribution network.
Thus, conversion from single-phase to three-phase is
necessary.
