LC移相双变压器式CO_2激光电源的电流波形及波纹系数特点分析

Characteristic Analysis of Current Waveform and Ripple Factor Produced by LC Phaseshift Double－Transformer Power Supply for CO_2 Laser

对电感、电容在单和双变压器电路中的作用及其对电流波形和波纹系数的影响进行了系统的分析和测试，并证明了该电路接入单相网路电源时可在变压器次极端无任何形式滤波电路条件下获得稳定．不过零点且波纹系数小的直流电流完全能满足CO2激光器工作的要求．

The functions and effect of inductance and capacitance in the circuit of single and double transformer on the current wavcform and ripple factor have been studicd and tested systematically in this paper and it is proved that this power supply without any forms of filter circuit in the sccondary eide of transformer can obtain direct currcnt with stability, no currcnt zero and low ripple factor to satisfy complctely the rcquircmcnt of CO2 lascr when it is conncctcd a single-phase nctwork service.
