| Abstract |
Variable Speed Drives (VSDs) allow energy savings for loads where operation below the gridfrequency may be required. However, when operating the motor load at the grid frequency,they introduce, compared to grid-connected operation, energy losses and ElectromagneticInterference (EMI). The Hybrid Inverter Drive (HID) offers maximum efficiency at either modeof operation. With the HID the motor load is operated in inverter-driven mode for motorfrequencies below grid frequency and operated in direct grid-connected mode for operation at gridfrequency. This eliminates inverter losses and EMI at the grid frequency. In previous work [5],the HID and its semi-closed transitions were introduced. A performance comparison of theHID operation using pure Sinusoidal PWM (SPWM), Space Vector PWM (SVPWM) and theinjection of the DC-link mid-point voltage into the SPWM reference signals during semi-closedtransitions is presented in this paper. The HID is modelled in MATLAB Simulink. |
