Abstract: A method and arrangement for preventing slip in a wheeled vehicle having two or more driving wheels that are operated with electric motors. The motor of each driving wheel includes a torque limit applicable to limit torque of the motor. For each driving wheel, the method includes setting an angular acceleration limit for the wheel, detecting angular acceleration of the driving wheel continuously, comparing the detected angular acceleration with the angular acceleration limit continuously, if the detected angular acceleration is higher than the angular acceleration limit, reducing the torque limit from its current value until the angular acceleration of the wheel is below the angular acceleration limit, increasing the torque limit at a first rate to a value lower than the value from which it was reduced, and increasing the torque limit at a second rate to the maximum value, the second rate being lower than the first rate.

Abstract: A method is provided for balancing voltages of a DC link of a multi-level inverter, where the DC link is divided into two halves by a neutral point connection. The method includes injecting a periodic common-mode voltage injection signal to a common-mode voltage reference and a periodic power injection signal to a power reference of the inverter. The power injection signal has the same frequency as the common-mode voltage injection signal. A phase shift between the common-mode voltage injection signal and the power injection signal is constant. The amplitude of at least one of the common-mode voltage injection signal and the power injection signal is controlled on the basis of a difference between voltages over the two halves of the DC link. An apparatus is also provided for implementing the method.
