The plasma opening switch (POS) performance was investigated with different driven current and different POS cathode diameters (f20 mm and f40 mm). The results show that the rise time of the load current decreases and the voltage multiplication factor of POS increases when the driven current increases. In the case of larger cathode diameter, lengthened conduction time and longer rise time of load current are obtained, meanwhile the POS voltage and current transfer efficiency decrease. The maximal voltage multiplication factor and current transfer efficiency obtained in experiments are about 4.9 and 97%, respectively. The rise time of load current is less than 100 ns.
