Abstract
In order to overcome the disadvantages of the power system of the intense pulsed light equipment,a "mainsubordinate" capacitive charging power circuit based on the IGBT chopper circuit was designed.The on and off-time of IGBT was controlled with the micro-chip computer to achieve high-speed and controlled charging process.The experiments prove that this circuit is not only safe but also can achieve the electric output power larger than 2kW when the operating voltage is 150V,and the output energy is uniform.The "main-subordinate" capacitive charging power circuit based on the IGBT chopper circuit can be adopted in the power of the intense pulsed light equipment.
