Title:
MOTOR DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/114853
Kind Code:
A1
Abstract:
A motor (10) includes a field pole formed by applying a field current to a field
winding (50). A boost converter (120) voltage-converts the output voltage
of a battery (B) and outputs it to a section between a power supply line (107) and
a grounding line (105). The field winding (50) is electrically connected to
a current path between the battery (B) and the power supply line (107) and configured
so that a voltage switched by a switching element (Q1) is applied to both ends of
it. A control device (100) switches/controls the switching element (Q1) and
a switching element (Q3) which is connected in parallel to the field winding (50),
so as to control the field current to adjust a magnetic flux density between a rotor
and a stator and convert the output voltage of the battery (B) into a voltage based
on the voltage instruction value.
