Design and simulation of 30 kv solid state DC source

Marx generator is an impulse source used for testing of various equipments. High voltage DC source is input to Marx generator. Traditionally, DC sources used for Marx generator were of large size but now due to advancement in solid state devices it is possible to reduce size and weight of DC source. This paper explains the designing and simulation of 30 kV solid state DC source to Marx generator. It makes use of zero current switching — series resonant (ZCS-SR) full — bridge topology with high frequency transformer and six stage voltage multiplier circuit. For switching purpose MOSFET is used. Effect of resistive and capacitive load on output voltage is analyzed.
