The dissertation discussed the research and development of TD-series laser surgery devices as know TD02, TD06, TD08 Nd:YAG laser system and TD98 Ruby laser system used in derma surgery. The main work can divide into 8 parts as follow:
1. Developing a soft switch half-bridge series resonant charge circuit for TD02 and TD98 systems, which can output 2.07A constant current, maximum 1860V charge voltage and about 3.85KW peak power.
2. Developing a single-mesh circuit with 230μs pulse-width disc...
