Technical Examples
  1. An inverter control device controls the operation of an inverter connected to an electric motor. A switching vector SV is determined as an output switching vector SVo to be supplied to the inverter based on a current deviation of the coil winding of each phase of the electric motor and a switching vector determination table. A keeping time TK is calculated based on a torque and a revolution speed of the electric motor. The counting of a time counting is then initiated. In a high revolution speed (TK>Selection time TS), the control operation for the inverter returns to a start step after the elapse of a certain time period that is set in advance. In a low revolution speed of the electric motor (TK<TS), a zero vector is newly selected as the output switching vector SVo after the elapse of the keeping time TK. The control operation for the inverter then returns to the start step after the elapse of the selection time period TS.
