<p>The motor has a frequency changer (2) for controlling the motor. The frequency changer includes a single phase converter that is provided parallel to both motor phases (A, B) and a condenser that is connected in series with the phase (B). The changer includes another inverter (5) with six pairs of switches, where one pair of switch is intermittently switched. The switches are controlled such that the switching loss is small. An independent claim is also included for a method of controlling a three phase inverter.</p> |
