从拓扑上说， Ｉ Ｈ Ｑ Ｒ Ｒ（ Ｉｎｔｅｇｒａｔｅｄ Ｈｉｇｈ Ｑｕａｌｉｔｙ Ｒｅｃｔｉｆｉｅｒ Ｒｅｇｕｌａｔｏｒｓ）电路是具有最优拓现 Ｕ Ｐ Ｐ Ｓ（ Ｕｎｉｎｔｅｒｒｕｐｔｉｂｌｅ Ｐｏｗ ｅｒｆａｃｔｏｒｃｏｒｒｅｃｔｅｄ Ｐｏｗ ｅｒ Ｓｕｐｐｌｉｅｓ）电路的高功率因数和最扑结构的单级 Ａ Ｃ Ｄ Ｃ 变换电路，对四拓扑变换器加以适当控制，可以实现单级变换和双 Ｄ Ｃ Ｍ （ Ｄｉｓｃｏｎｔｉｎｕｏｕｓ Ｃｏｎｄｕｃｔ Ｍｏｄｅ）模式，与 Ｉ Ｈ Ｑ Ｒ Ｒ 的要求相一致，是实优拓扑特点的理想部件。基于此部件，构造了一种集成不间断供电和高功率因数的开关稳压电源，在正常、充电和后备电源三种模式下均只有单个变换级。对该新型电路运用 Ｐ Ｓ Ｐ Ｉ Ｃ Ｅ进行了仿真分析，仿真结果与理论分析相吻合。
Topologically, the I H Q R R (Integrated High Quality Rectifier Regulators) circuit is the high power factor and the most plutonium circuit with the optimal topology U P -P S (Uninterruptible Power Factor Corrected Power Supplies) circuit Structure of single-stage A C D C conversion circuit, the four topology converter to be properly controlled, you can achieve a single-stage transformation and double DCM (Discontinuous Conduct Mode) mode, consistent with the requirements of I H Q R R is Realistic topological features of the ideal components. Based on this component, an integrated switching constant voltage power supply with uninterruptible power supply and high power factor is constructed, which has only a single conversion stage in three modes of normal, charging and backup power supply. The new circuit using P S P I C E was analyzed. The simulation results are in good agreement with the theoretical analysis.
