| 主权项 | 1. A system for measuring insulation resistance, comprising: a first operational amplifier that is connected with (i) a positive terminal of a battery without having any resistor between the first operational amplifier and the positive terminal and (ii) a second operational amplifier through a ground; the second operational amplifier that is connected with (i) a negative terminal of the battery without having any resistor between the first operational amplifier and the positive terminal and (ii) the first operational amplifier through the ground; a first switch that is connected between the positive terminal and a non-inverting terminal of the first operational amplifier; a second switch that is connected between the negative terminal and an inverting terminal of the second operational amplifier; and a controller configured to determine insulation breakdown between the positive terminal and the ground by closing the first switch. | ||
