PROBLEM TO BE SOLVED: To provide a cooling structure of a switching element wherein a cabinet is miniaturized and width of pulses to be applied to a magnetic pulse compression circuit can be reduced. SOLUTION: Semiconductor switches SW1-SW4 are fixed on insulating plates 2, 2', which are cooled by using a water cooling plate 3. Partitions 2a-2c, 2a'-2c' which are constituted of insulating members are arranged in the peripheral parts of the semiconductor switches SW1-SW4. Consequently, creeping distance between the semiconductor switches SW1-SW4 and the water cooling plate 3 can be ensured without enlarging the insulating plates 2, 2', and length of a wiring W can be reduced. Hence, floating inductance generated in the wiring W can be reduced, and width of pulses to be applied to a magnetic pulse compression circuit can be reduced. By arranging the partitions between end portions of the insulating plates 2, 2' of the wiring leading-out side and the semiconductor switches, the wiring W can be more shortened, and floating inductance can be reduced. |
