CONVERTER CONTROL DEVICE AND ELECTRIC VEHICLE USING THE SAME
DRIVE
April 4, 2012
A voltage control operation unit (106) receives, from a subtraction unit (104), a value obtained by subtracting a detection value of a voltage (Vm) from a voltage command value (VR), and performs a control operation for setting the voltage (Vm) to be equal to the voltage command value (VR). The voltage control operation unit (106) outputs the calculated control amount as a current command value (IR). A current control operation unit (110) receives, from a subtraction unit (108), a value obtained by subtracting a detection value of a current (IL) from a current command value (IR), and performs a control operation for setting the current (IL) to be equal to the current command value (IR). A driving signal generation unit (112) generates a signal (PWC) for driving a boost converter based on a duty command value (d) received from the current control operation unit(110).
