| 摘 要： | 提出了一种外接式三相功率因数校正方案. 采用改进型有源滤波算法和高速空间矢量控制理论，在不破坏原有电网电力设备结构的基础上，实现了单位功率因数，并提高了谐波与无功电流的检测速率和逆变器开关管控制速度，减少了开关损耗. 该方案在电网电压畸变的情况下，实现相位同步、谐波完全补偿. 通过理论分析和实验证明了该方案是切实可行的.

| Abstract: | A shunt three phase power factor correcting scheme was presented.An optimized active power filtering algorithm and high speed space vector pulse width modulation(SVPWM) theory were used to achieve unity power factor without destroying the structure of electronic facility.The scheme improves both synchronous detection frequency and dynamic response of the PWM inverter,and reduces switching losses.Current voltage synchronization and complete compensation of harmonic currents are realized under distorted voltage conditions.Theoretical analysis and experiment results have verified its feasibilities of this scheme. |
