VOLTAGE CONVERSION DEVICE AND COMPUTER-READABLE RECORDING MEDIUM HAVING PROGRAM RECORDED THEREON FOR COMPUTER TO CONTROL VOLTAGE CONVERSION

摘要

In a case where the deviation between a target voltage (Vdc_com 1 ) and an output voltage (Vm) is larger than a specified value (A), a voltage command (Vdc_com 2 ) of a voltage step-up converter ( 12 ) is calculated by adding the specified value (A) to the output voltage (Vm). When the output voltage (Vm) having been decreasing starts to increase, the voltage command (Vdc_com 2 ) is calculated in such a manner that the rate of change of the voltage command (Vdc_com 2 ) is equal to or smaller than a standard value. Using the calculated voltage command (Vdc_com 2 ), feedback control of the voltage step-up converter is conducted in such a manner that the output voltage (Vm) is equal to the target voltage (Vdc_com 1 ).
