Title: Current detecting device
Inventor: YAMADA SHUSAKU
IPC: G01R19/00
Filed: 1992-11-19
Abstract: PURPOSE:To correct the temperature characteristic of a current detection circuit by connecting in series a diode with a load resistor between the output and earth of a diode bridge. CONSTITUTION:A diode bridge 9 rectifies an AC current proportional to a current 7a to be measured by means of a current transformer 8 and a forward voltage drop 12b through a load resistor 10 and diode 13. By passing the dropped output voltage 12b through a low-pass filter 11 having different charging and discharging time constants, an output voltage which is nearly proportional to the effective value of the current 7a is obtained. Since the diode 13 has a negative temperature characteristic which reduces the voltage drop 12b when the temperature rises, the temperature characteristic of current detection circuit can be corrected by offsetting the positive temperature characteristic of the transformer 8 by using the diode 13.
