Title: Inverter controller
Inventor: OBAYASHI KAZUYOSHI
IPC: H02P6/28
Filed: 1995-06-08
Abstract: PURPOSE: To perform two-phase modulation with excellent controllability having no distortion in current waveform. CONSTITUTION: A real current of a three-phase AC motor 4 is detected by a current sensor 5, and a voltage command value is calculated from a detected current value and a current command value of ECU3. Based on a current command value, the phase and its period for fixing the output of an inverter 2 for two-phase modulation are determined and, if the phase difference is great between the current command value and the voltage command value, then the two-phase modulation period is changed by limiting or shifting. In the two- phase modulation period changed, the amount of offset of the reference voltage signal for generating PWM signal is determined, PWM signal is generated by the offset reference voltage signal and the voltage command value of each phase and is used as an output to the inverter 2.  When the phase difference is large, no voltage command exceeding the power supply voltage (main battery 1) of the inverter 2 is output to the inverter 2 by the limiting or shifting of the two-phase modulation, so that the electromagnetic noise or switching loss can be reduced.
