摘　　要：应用高频逆变和调制脉冲技术在升压变压器的低压端实现连续／脉冲转换工作方式，研制出一台１００ｋＨｚ逆变调制连续／脉冲气体激光电源，该电源在升压变压器次级端去掉滤波高压电容和限流电阻的条件下能长期稳定工作，并具有抗网路波动强、调节范围宽、转换效率高、适应性强以及体积小、重量轻等优点。A 100kHz high frequency continuous/pulse power supply with an inverter of modula-tion type for a gas laser has been developed.The maximum power output is 180 W in thecontinuous working mode,A set of modulated pulses with a continuously adjustable frequen-cy range from 0～10 kHz and a range of duty factor from 1%to 99%have been made possi-ble in the pulse mode. The power supply developed can work stably without a resistance-ca-pacitance filter and current limiting resistance at the high voltage terminals. The variation ofthe working current is less than 1 mA with the network voltage fluctuating between 160～250V.
