A novel inverter with sinusoidal voltage and current output
説明
Output voltages of a conventional voltage-source pulse-width-modulated (PWM) inverter applied to AC motor drive systems contain high-level switching frequency ripples due to the PWM operation, while output currents are kept nearly sinusoidal. The high-level harmonics, in the output voltage cause acoustic noises and iron losses. To improve the output voltage waveforms, the authors propose a novel inverter with sinusoidal voltage and current outputs, which has an LC passive filter and an active filter function. The principle of the inverter and some simulation results are shown. Simulation results show satisfactory operation when it is applied to a field-oriented vector control system, for an induction motor. >
