Capacitor apparatus

Abstract

A capacitor apparatus according to the present invention is configured to charge electric charge in capacitors C1 and C2 and discharge electric charge from the capacitors C1 and C2 at normal operation time. The capacitor apparatus includes an internal resistance detection means 2 for detecting the internal resistance value of the capacitors C1 and C2 and an inter-capacitor charging/discharging control means 1 for controlling charging/discharging operation between the capacitors C1 and C2. When the internal resistance detection means 2 detects a resistance value more than a predetermined value, the inter-capacitor charging/discharging control means 1 performs charging/discharging control between the capacitors C1 and C2 to cause the capacitors C1 and C2 to self-heat.
