Abstract:
On end of a reactor (L1) is connected to a positive electrode of a battery (B1) and the other end is connected to a power line via a transistor (Q1) and to the ground via a transistor (Q2). By PWM control of the transistors (Q1, Q2), 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.

외부 어댑터와 연결된 전기기기 및 모터 시스템이 개시된다. 모터 시스템은 교류전원을 직류전원으로 변환하여 입력 전원을 제공하는 외부 어댑터 및 입력 전원을 이용하여 모터를 구동하는 모터 장치를 포함하는 모터 시스템으로서, 모터 장치는, 외부 어댑터와 연결되어 입력 전원을 입력받는 제 1 접속부와, 입력 전원을 모터 장치의 필요용량에 부합하는 직류전원으로 변환하여 변환 전원을 생성하는 전원변환부와, 변환 전원으로 모터를 구동하는 부하부를 포함한다. 따라서, 이러한 외부 어댑터와 연결된 전기기기 및 모터 시스템에 따르면, 규격화되어 대량생산되는 임의의 어댑터를 이용하여 전원단을 구성할 수 있으므로, 전기기기마다 맞춤형 전원변환장치를 따로 제조함으로 인한 자원과 비용을 절감할 수 있다.
