<p>PURPOSE:To obtain a driver for high voltage semiconductor switch having high noise resistance which causes no erroneous function nor failure even when the current rise rate of main circuit is quite high at the time of turn ON of a pulse laser power supply, for example. CONSTITUTION:Electrical energy for driving semiconductor elements is transmitted to a high voltage semiconductor switch comprising a plurality of semiconductor elements 24, 25 electrically connected in series with a power supply of ground potential through transformers 31, 31A employing race track type or rectangular cores 32, 37 mounting a primary winding 33 with secondary windings 34, 35 being disposed on a magnetic path in the longitudinal direction of the core.</p> |
