Abstract
On end of a reactor (L) is connected to a positive electrode of a battery (B) and the other end is connected to a power line via a transistor (Q) and to the ground via a transistor (Q). By PWM control of the transistors (Q, Q), an arbitrary increased voltage is obtained in the power line. It is possible to obtain an optimal inverter input voltage (power line voltage) according to the motor drive state, thereby increasing efficiency. Thus, it is possible to optimize the inverter input voltage according to the motor drive condition.
