摘要:
在交流变压器副边的桥式整流电路后 ,去除滤波电容 .用脉宽调制 (PWM)加电流闭环的方法 ,实现电源从交流到直流的转换 ,使交流侧电流的谐波分量得到有效抑制 ,使电流波形具有良好的正弦特性 ,同时也使电源的功率因数近似为 1,使电源的性能得到有效提高 .在对电路进行分析的基础上 ,用仿真的方法进行验证 ,得到和理论分析一致的结果 .由此 ,设计了单片机控制系统 ,通过对主电路中IGBT门极信号的控制 ,实现预定的控制策略
Abstract:
The filter capacitor C connected in the DC side of diodes bridge rectifier was removed. By using pulse width modulation ( PWM) method and current loop, energy conversion from AC to DC was realized, performance of the power supply was upgraded, the harmonic currents was restrained, the current in the AC sidewas made to be of good sinusoidal shape and the converter of unify power factor was insured. After theoretical analysis of the operating principle, simulations was carried out to ver-i fy the theoretical result. A microcomputer based control system, which was used to trigger the gates of IGBT and realize the strategy of control, was also provided.
