The power factor improving power converter 1 includes a switching device S, a power factor improver, and a power converter. The power factor improver operates to smooth a rectified voltage by storing energy in a first inductive device L1 and by discharging energy from a second inductive device L2, in which the first and second inductive devices are magnetically coupled together. The storing and discharging is performed by turning ON and OFF the switching device S. A predetermined DC voltage is converted by energy stored and discharged by a third inductive device L3 in response to the turning ON and OFF of the switching device S.

摘要： An input surge suppression device and method that uses a simple JFET structure. The JFET has its gate clamped to a predetermined value, its the drain receives the input voltage from an input power source, its source is connected to the input of a down-stream device, and a resistor connected between the drain and the gate or between the source and the gate. Thus, when the drain voltage approximates the clamped gate voltage, the source voltage nearly equals the drain voltage. When the drain voltage rises above the clamped gate voltage, the source voltage is lower than the drain voltage. The downstream device may be a DC-DC converter and the gate is biased by the enable (EN) pin of a DC-DC converter.

摘要： The present technology is related generally to a switching mode power supply with virtual current sensing. The switching mode power supply comprises a power stage that includes a first power switch and a second power switch coupled in series. The switching mode power supply senses a first current flowing through the first power switch during on-time and provides a virtual current sense signal that is proportional to a second current flowing through the second power switch during on-time. The switching mode power supply further combines the real current sense signal and the virtual current sense signal to form a current sense signal, which is sent to the controller to realize desired control.
