Abstract: front page image
(EN)The present invention relates to a power saving current measuring apparatus and to a power converter using same. The power saving current measuring apparatus includes: a sensing resistor; a switch connected in parallel to the sensing resistor; a controller for controlling the on/off operation of the switch; and a current measuring unit for measuring the current flowing through the sensing resistor, wherein the controller controls the current to flow into the switch by rerouting the sensing resistor when the switch is turned on, and controls the current to flow into the sensing resistor when the switch is turned off. Accordingly, power loss can be prevented and measurement efficiency can be improved in accordance with the use of the sensing resistor only when the current needs to be measured by connecting the sensing resistor to the current measuring target and connecting the switch to the sensing resistor in parallel.
(FR)La présente invention concerne un appareil de mesure de courant à faible consommation et un convertisseur de puissance utilisant celui-ci. L'appareil de mesure de courant à faible consommation comprend : une résistance de détection ; un commutateur connecté en parallèle à la résistance de détection ; un dispositif de commande pour commander la mise sous/hors tension du commutateur ; et une unité de mesure du courant pour mesurer le courant circulant à travers la résistance de détection, le dispositif de commande commandant au courant de passer dans le commutateur par la redirection de la résistance de détection lorsque le commutateur est mis sous tension, et commandant au courant de passer dans la résistance de détection lorsque le commutateur est mis hors tension. Par conséquent, la perte de puissance peut être empêchée et l'efficacité de mesure peut être améliorée conformément à l'utilisation de la résistance de détection uniquement lorsque le courant doit être mesuré par le raccordement de la résistance de détection à la cible de mesure de courant et par le raccordement en parallèle du commutateur à la résistance de détection.
(KO)본 발명은 전력 절감 전류 측정 장치 및 이를 이용한 전력 변환기에 관한 것으로서, 본 발명의 일 실시예에 따른 전력 절감 전류 측정 장치는, 센싱 저항과, 상기 센싱 저항과 병렬 연결되는 스위치와, 상기 스위치의 온오프 동작을 제어하는 제어부와, 상기 센싱 저항에 흐르는 전류를 측정하는 전류 측정부를 포함하며, 상기 제어부는 상기 스위치를 온(on) 구동 시 전류가 상기 센싱 저항을 우회하여 상기 스위치로 흐르도록 제어하고, 상기 스위치를 오프(off) 구동 시 전류가 상기 센싱 저항에 흐르도록 제어한다. 이에 따라, 전류 측정 대상에 센싱 저항을 연결하고 센싱 저항에 스위치를 병렬 연결하여 전류 측정이 필요한 시간에만 센싱 저항을 사용함에 따라 전력 손실을 방지할 수 있고 측정 효율을 향상시킬 수 있는 이점이 있다.
