摘要： The device according to the invention controls a polyphase inverter (10, 14, 17) intended for powering from a DC current source (CC) a polyphase rotating electric machine (1). The device is of the type of those generating commutation functions driving commutation elements (9, 13) of the inverter in such a way as to obtain a reduction of the losses in the commutation elements and a decrease of an effective current in a decoupling capacitor (16) of the source (CC). According to the invention, this reduction and this decrease are obtained by means of a set of control strategies (21, 24) determining the commutation functions by using additional degrees of freedom of the polyphase machine (1) with respect to a three-phase reference machine. The polyphase machine comprises first and second phase windings forming a first three-phase system (2, 3, 4) and a second three-phase system (5, 6, 7) with distinct neutral points (11, 15) offset angularly by a predetermined angle of offset (Θ). The first and second phase windings are linked respectively to three first and three second power arms (8, 12) formed by the commutation elements.

In this way, a device for controlling an alternating-current motor is provided to restrain occurrence of an offset current upon rectangular wave voltage control.

摘要： A motor controller (100) is provided for smooth operation of an electric motor (102), which mitigates torque ripple, noise and vibration effects, and increases a life span of the motor (102). The motor controller (100) includes a speed controller (120), current transformation units (128 and 130), a current controller (132), and a pulse width modulation (PWM) signal generator (134). The current controller (132) determines a duty cycle of PWM gate signals used for controlling a rotor (104) speed within a particular sector (302A) of the motor (102) based on a reference quadrature-axis current and an actual quadrature-axis current. The PWM signal generator generates the PWM gate signals having the determined duty cycle, controls the rotor (104) speed, and incrementally varies a current speed of the motor (102) to achieve a target speed by modulating operations of a specific pair of inverter switches (502C and 502E) using the PWM gate signals.

摘要： A motor driving device includes an inverter circuit having switching elements; and a control device controlling the switching of the switching elements. The control device sets a carrier frequency to f1 when a two-phase modulation scheme is selected, and sets the carrier frequency to f0, which is half of the carrier frequency f1, when a three-phase modulation scheme is selected. Thereby, the frequency of the secondary component of a current flowing in a filter circuit of when selecting the three-phase modulation scheme may be deviated from the resonance frequency of the filter circuit. Accordingly, the current ripple generated in the filter circuit may be reduced even when selectively switching the modulation scheme for the PWM modulation among a plurality of modulation schemes.
