Recently, a remarkable advance is seen in the application on the laser equipment, particle beam accelerator, and pulsed X-ray equipment. These apparatus requires an intermittent high voltage or large current power source to do work, and those power sources are required to have a high reliability and a durability. For this reason, a power supply using passive circuit elements is often used for these apparatus. A multistage circuit made by a saturable reactor and a capacitor is a good example of pulse power supply. In this paper, a discussion is given on the optimal circuit parameter and the optimal operation mode of a fundamental two-stages pulse compression circuit. Analysis for the two-stages LC circuit is developed by use of the state variable method, and it is assumed that a saturable reactor has a magnetization characteristics approximated by a polygonal line with two segments. Defining evaluation indices on voltage boost ratio G_v, current gain G_j and pulse width compression ratio ζ, the optimal operation mode was determined by these indices, and the optimal circuit parameter was obtained. As the results, it is shown that the C_1 equals to 10×C_2 in case of two reactors, with a same value, and it is obtained that G_v=0.35, G_j=0.26 and ζ=0.66. It is also shown that the reactor loss is a very sensible to the performance of this circuit.
