Each individual electrolytic capacitor was fused with a ceramic ABC 20A slow blow fuse rated at 250 volts. This was done for safety reasons since each recharge capacitor bank could contain as much as 50 KJ of energy which might discharge through an individual capacitor if it failed. The circuit diagram of the recharge capacitor bank is shown on Fig. 4.6. Fig. 4.6 Recharging capacitor bank circuit.
