    Abstract: A controllable switching mechanism (100) integrally housed within a motor (100) to optimally couple the windings (112, 114, 116) of an AC motor for improved torque-speed characteristics. The switching mechanism (100) includes a plurality of double throw switches (121, 123, 125) each with a first and second closed position. The first closed position results in connecting the windings (112, 114, 116) of the AC motor (102) in one configuration for improved torque at lower rotor speeds. The second closed position results in connecting the windings (112, 114, 116) of the AC motor (102) in another configuration for improved torque at higher speeds. The winding configurations may be wye for lower speeds and delta for higher speeds. An accompanying controller (104), based on various inputs, optimally senses the best time for switching between configurations and sends appropriate control signals to the switching mechanism (100) housed with the AC motor (102).

    Abstract: A voltage source inverter generating a poly phase AC signal is provided that includes an SVPWM controller. The controller is adapted to modify the switching pattern at low sine-wave frequencies creating a more even distribution of the conduction losses. The switching pattern periodically changes the sequence (or rotational sense) of the space vector components from clock-wise to counter-clock-wise direction, and vice-versa.

    Abstract translation: 提供了一种产生多相AC信号的电压源逆变器,其包括SVPWM控制器。 该控制器适于在低正弦波频率下修改开关模式,从而产生更均匀的导通损耗分布。 切换模式周期性地将空间矢量分量的顺序(或旋转方向)从时钟方向改变到逆时针方向,反之亦然。
