Title:
DRIVE DEVICE
Document Type and Number:
Japanese Patent JP2012170173
Kind Code:
A
Abstract:
To suppress heat generation of a reactor element of a booster circuit.
When a low-voltage system voltage VL is within the range that is larger than a voltage V1 and less than a voltage V2, a DC-DC converter is controlled so that the low-voltage system voltage VL is the voltage V1 or the voltage V2 (step S100-S120). Thus, a ripple current of a reactor can be suppressed from increasing to suppress an increase in heat generation of the reactor of a booster circuit.
