Safety aspects • Paralell operation – A switch failure will only dump one 42 th of the total stored energy. – Off the shelf capacitors will be used. – A failed module could be deconnected and the loss is 1/42 of the total power capacity • • All High voltage inside the tank Primary circuit <1400 V Pulse over current respond time 2 us. DC-Voltage discharge time within 10 sec
