| 摘 要： | 通过常用的buck-boost变换器级联电路的对偶变换，可以导出一种带有单级功率因数校正的新型变换器拓扑电路。对设计公式进行分析，可以得到元件参数值和电流应力之间的关系。仿真和实验结果验证了该电路的运行特点和其功率因数校正能力。

| Abstract: | A new single stage PFC regulator is derived by taking the dual of a well-known circuit based on a cascade of conventional boost-buck converters. Analytical design expressions are derived, illustrating the relation between current stress and component values. PSPICE simulation and experimental results is performed to confirm the operation of the circuit and its power-factor-correcting capability. |
