Industrial applications require large numbers of
motors. For example, motors are used to manipulate industrial
robots, an electric vehicles with in-wheel motors and electric
trains. Two methods exist for controlling PM motors providing
an inverter to control each motor, and connecting the motors in
parallel and driving them with a single inverter. The first method
makes an experimental apparatus complex and expensive; the
second does not allow independent control of each motor because
of differences in rotor angle between the two motors. Thus, we
propose a novel nine-switch inverter that can independently control
two three-phase loads. This paper introduces the structure
of the nine-switch inverter, which is made from nine switches. The
validity of the proposed inverter is verified through simulations
and experiments.相关搜索： A
