摘要
采用新型谐振技术,成功地研制出激励高功率激光器的零电流开关谐振式开关电源,其工作频率为50kHz,功率转换效率为82%以上,输出电流为0~80mA连续可调,放电电流波动小于±1mA。实现了功率管的低损耗工作,无需镇流电阻实现稳定放电,使起辉电流及电流的稳定度与放电管气体浓度和气压等无关。
The prototype of ZCS SRC (zero current switching series resonant converter) switching mode power supply for high power lasers is developed successfully based on a novel resonant technique. Compared with the conventional and PWM hard switching power supplies, the outstanding technical indexes of the ZCS SRC which holds a leading position in China are as follows: operating frequency is 50 kHz, efficiency is 82%, output current is 0~80 mA, and the fluctuation of current is ≤±1 mA. The power supply for the high power gas laser provides a steady discharge current without the need of any amperites. The discharge current can be adjusted from zero and is independent on gas density and gas pressure.
