Abstract
The voltage amplification factor during rapid deceleration control of a motor is set to a value obtained by adding a first voltage amplification factor calculated with reference to the voltage of the DC circuit section of the inverter using a predetermined function and a low-pass filter and a second voltage amplification factor calculated with reference to the inverter current using a PI control. And both calculations are performed in parallel.
