By using the technology of energy storage inductor and electro-exploding wire opening switch (EEOS) drived by pulsed capacitors, we studied the inductive-energy-storage pulsed power source. Based on the researches of EEOS with different material, different parameters and different quench medium, an excellent opening switch has been developed. On the basis of EEOS researches, An Inductive energy storage pulsed power source has been developed and tested. Experimental results show that output voltage and current of the pulsed power source exceed 700kV and 60kA with the rise time of less than 50ns and pulse width of more than 150ns. The energy efficiency is more than 40%.
