Title: Converter control method and controller
Inventor: OUCHI TOSHIO
IPC: H02M7/48
Filed: 2019-03-27
Abstract: To provide a converter control method for stepping up DC input voltage supplied from a battery and supplying power to a motor via an inverter on which constant voltage control is performed.SOLUTION: A motor system includes a converter for stepping up DC power supplied from a battery and supplying it to an inverter. The inverter performs conversion to AC power and supplies the AC power to a motor. In the case of power running of the motor, gain is determined depending on output power and output voltage from the converter to the inverter and a step-up ratio of the converter and output voltage of the converter is controlled by feedback control using the gain. In the feedback control of output voltage of the converter, destabilization is inhibited from being caused by negative resistance characteristics depending on output power and output voltage of the converter and phase delay depending on the step-up ratio.SELECTED DRAWING: Figure 6
