摘　　要：设计了一种采用直接控制原理的两级交错并联分时工作单相数字有源功率因数校正器(APFC)。描述在直接控制原理和分时工作方式的基础上,采用Matlab/Simulink对整个APFC系统进行仿真分析和试验研究。仿真试验验证了其正确性和可行性,且在相同输出功率条件下效率提升了1%～2%;同时,电感与功率开关选型、参数配置得到了简化。A single-phase digital time sharing two-stage interleaved paralleled active power factor correction（APFC） using direct control principle was designed.Based on describing the principle of direct control and the method of time sharing,simulation analysis and experimental study of the whole APFC system were carried out by using of Matlab/Simulink.The results showed that the principle of direct control was correct and the mode of time-sharing operation was feasible.Under the same output power conditions,the efficiency was improved by 1% ～ 2%,meanwhile,the selection and the parameter configuration of the inductor and power switches were simplified.
