Research on the medical Nd:YAG laser power system using LLC resonant converter
In this paper, we designed a LLC resonant converter as the main power supply of the medical Nd:YAG laser. First harmonic approximation (FHA) is used to model the LLC resonant converter. FHA equivalent circuit model and the transfer function of the LLC converter is proposed. Soft start technology is used to suppress the surge current. The laser output is simulated and experimented, the pulse laser energy is up to 2.5J, and the pulse per second (PPS) can be adjusted from 6 to 18. The power system is verified stable and reliable by simulation and experiment.
