摘要
根据传统升压式AC/DC变换器的功率因数校正原理,讨论了两种升压电感置于整流桥前的单相AC/DC变换器,在对其进行仿真分析之后认为,它们的控制原理可以保持不变,其控制电路也可通过适当改进传统单相AC/DC变换器的控制电路而得到,而且因结构紧凑而便于功率集成。最后给予了物理实现,功率达到2kW以上,仿真结果与实验结果验证了理论分析的正确性。
On the basis of power factor correction principle of traditional boost single-phase AC/DC converter,two single-phase AC/DC converters are investigated, in which the boost inductor is placed before the uncontrolled bridge. After analysis, they can employ the same control algorithm as traditional one, and so its control circuit can get only by appropriate modification. Such converters are convernient for power integration due to compact structure.Finally they are implemented with unity power factor with an output power up to 2kW. The simulative and experimental results verify the validity of the theoretical analysis.
