由于DBPFC电路和传统Boost PFC电路的差模干扰几乎相同[2],所以只要看共模电压就可以看出各个电路的EMI的严重程度。本文对各种DBPFC电路的共模等效模型进行了推导和分析,为了方便比较同时给出了传统PFC电路共模噪声[3]。 首先本文简单的介绍了各种不同DualPFC拓扑的工作原理。接着详细的分析它们的共模噪声等效电路,在此...
This paper presents a voltage sensorless feedforward controller, which relies on the input current and output current of the dual boost PFC converter in a battery charger application. Because this control scheme utilizes the measured current information, this approach is well suited for the battery ...

A dual-mode control scheme is proposed in this letter to control a boost power factor correction (PFC) converter. The scheme combines both continuous and critical conduction modes and has the merits of simple control, high efficiency in a light-load condition, and being fit for personal computer...
This paper presents an efficient single-switch boost-dual-input flyback power factor correction (PFC) converter. To achieve a high power factor, a boost PFC cell operating in discontinuous conduction mode is presented. A dual-input flyback dc-dc module, which consists of parallel primary windings...
X58 boards dont support overclocking but turbo boost. Only HUANAN ZHI deluxe X79 board supports Crossfire. 4: Why does the motherboard temperature sensor sometimes work abnormally? Yes, sometimes the motherboard temperature works abnormally, so it gives wrong temperature information on motherboard and...
