20100127720 | CURRENT MEASURING CIRCUIT - A first resistor, a second resistor, a transistor, and a third resistor connected in series between a ground potential and an output terminal of a power circuit are provided. In addition, a current-detecting resistor is inserted in series between a high-voltage site and an output terminal of a power circuit that supplies a predetermined direct voltage to the high-voltage site. A differential amplifier controls a current flowing through the transistor so that a potential difference generated between both ends of the third resistor becomes proportional to a potential difference generated between both ends of the current-detecting resistor. At this point, by measuring the voltage of a connection node of the first resistor and the second resistor, the value of a current flowing through the high-voltage site can be calculated from the measured value. | 05-27-2010 |
