| titleOfInvention | PWM inverter |
| abstract | In a PWM inverter the maximum three-phase RMS pole-to-pole output voltage (U1, U2, U3) is increased, by generating substantially sinusoidal changing pole voltages (V1, V2, V3) having no values within predetermined zones adjacent to each power supply limit, and by switching each pole voltage to the power supply limit (Vmax) for a predetermined number of electrical degrees during each half cycle, resulting in step changes in the pole voltage waveforms from the substantially sinusoidal changing waveform to a fixed power supply limit. The waveforms of other associated poles are changed at the discontinuities in order to maintain a sinusoidal pole-to-pole voltage. The arrangement uses the d.c. source efficiently and recognises that modulation below 10% and above 90% is not possible. <IMAGE> |
