Abstract

A prototype of ZCS-SRC（zero current switching-series resonant converter） soft switching mode power supply for high power lasers is developed based on the novel resonant technique.Half-bridge resonant switching mode is adopted for the main circuit

the IGBT turns on and off at zero current

the operating frequency is 25 kHz

and the output current is 5～120 mA.The power supply for high power gas laser provides a steady discharge current without any amperite.The discharge current is independent on gas density and gas pressure.
