PURPOSE: A battery voltage measurement circuit is provided to measure voltage variation without mutual interference by insulating a gate turn-on signal of a switch device using a driving transformer. CONSTITUTION: A battery is connected to a first capacitor through a pair of resistors. The first capacitor is connected to a second capacitor through a pair of switches. The second capacitor is connected to a third capacity through a pair of switches. The third capacitor is connected to a voltage meter. Each switch interlinks a pair of transistors to a reverse direction. A gate driving transformer(P1,P2) controls each transistor in a remote site. |
