The present invention provides an apparatus for controlling a multiphase multilevel voltage source inverter. The apparatus includes a signal-generating unit and a converter. The signal-generating unit responds to an input signal to produce a switching strategy control signal and a duration timing control signal corresponding to the switching strategy control signal. The converting unit responds to the switching strategy control signal and the duration timing control signal to produce a switching signal. The voltage source inverter responds to the switching signal to generate a multiphase-and-multilevel AC voltage output.

A glove puppet manipulating system comprises a control module for generating control signals base on movements of human hand and a robot electrically connecting the control module installed inside a glove puppet. The robot has a body manipulating apparatus disposed on a foundation to manipulate the body of the glove puppet to rotate, a pair of hand manipulating apparatuses disposed on the body manipulating apparatus to manipulate the hands of the glove puppet to swivel, and a head manipulating apparatus interposed between the hand manipulating apparatuses on the body manipulating apparatus to manipulate the head of the glove puppet to nod.
