摘要： A method for controlling brake resistors and a brake chopper, the number of brake resistors (73, 75, 77) being two or more and the brake resistors being connected in series with switches (72, 74, 76) to be controlled, the series connection being connected between a positive and a negative rail (U dc+ , U dc- ) of a DC voltage intermediate circuit, the method comprising the step of determining a magnitude for a voltage (U dc ) of the DC intermediate circuit; and determining a first voltage limit (U lim1 ) and a second voltage limit (U lim2 ). The method further comprises the steps of switching brake resistors to the intermediate circuit in a periodically alternating manner, each switch being switched during a switching period and the on-period of each switch in a switching period being responsive to the magnitude of the voltage in the DC voltage intermediate circuit when the voltage is above the first predetermined limit and below the second predetermined limit.

摘要： A method of estimating a rotor angle of a synchronous reluctance motor, where the motor comprises a stator and a rotor. First, a stator flux and a stator current are determined. Two orthogonal stator flux components in a stator reference frame are calculated from the stator flux. Two orthogonal stator current components in the stator reference frame are calculated from the stator current. A rotor orientation vector is then calculated using a known rotor direct or quadrature axis inductance component, the stator flux components, and the stator current components. The rotor orientation is estimated on the basis of the rotor orientation vector.
