| 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。

| Abstract: | 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. |
