摘要
采用有源功率因数校正(APFC)及同步整流技术设计了一款实用反激式开关电源装置。样机实验结果表明,所设计的APFC开关电源的功率因数达到0.952～0.989,整个电源系统的效率高于85.8%,且总谐波电流畸变率<3.75%,电磁污染程度较低,因而此装置具有实用推广价值。
Adopting active power factor correction （APFC） and synchronous rectifier technology, a practical flyback switching power supply device was designed, experimental results on prototype show that power factor of the switching power supply with APFC reaches 0.912 - 0.979, efficiency of the whole supply system is higher than 85.8%, and the total harmonic current distortion （THD） is under 3.75%, which indicates the level of electromagnetic pollution is lower. Therefore, the designed supply has high practical value.
