This paper deals with the integrated 5 kW xenon flash lamp power supply. In order to drive a xenon lamp used in an application field of light sintering of printed electronics, the power supply in consideration of load characteristics is required. The simmer power supply that maintains the xenon lamp's ignition is designed based on an LCC resonant converter with both voltage and current source characteristics. Also, an auxiliary rectifier and trigger applying high voltage are required to ignite the xenon lamp. And the power supply is designed based on a boost-type resonance circuit and a Cockcroft Walton voltage multiplier, respectively, in consideration of sharing the inverter with the simmer. This paper analyzes the topology of the proposed power supplies and selects the parameters and confirms them through simulation. Finally it was verified through experiments that the output voltages of the simmer, the auxiliary rectifier, and the trigger were 20 V, 400 V, and 10 kV, respectively. |
