| 摘 要： | 提出了一种新颖的两开关电路拓扑，它能工作在宽输入交流电压范围，并实现功率因数校正(PFC)。新拓扑与单开关Buck—Boost变换器和传统的两开关串级Buck—Boost变换器及其它Buck—Boost变换器相比有显的性能改善，如：器件应力及损耗较低，不需要解决浪涌电流问题，电感尺寸也较小。分析了拓扑工作原理，并给出了实验结果。 |
| 关 键 词： | Buck－Boost变换器 控制电路 浪涌电流 功率因数 |

| Abstract: | A novel two switch converter is proposed for universal power input with power factor correction. With this topology, power stress and conduction loss will be decreased significantly compared with single switch Buck Boost converters (such as flyback, SEPIC, and Cuk) and conventional two switch Buck Boost converters. The converter can employ a smaller sized inductor and shows no inrush current problem compared with a Boost converter. Topology and operation principle are presented, and experimental results are given in detail. |
| Keywords: | converter power factor correction power stress THD |
