Abstract:
Provided is a circuit for measuring insulation resistance, including: a first operational amplifier that is connected with a positive terminal of a battery and a second operational amplifier; a second operational amplifier that is connected with a negative terminal of the battery and the first operational amplifier; a first switch that is connected between the positive terminal and a non-inverting terminal of the first operational amplifier; and a second switch that is connected between the negative terminal and an inverting terminal of the second operational amplifier, wherein the first operational amplifier and the second operational amplifier are connected with each other through a ground.
