6 FAQs about [Pfc energy storage inductor replacement]
What is power factor correction (PFC)?
Power Factor Correction (PFC) shapes the input current of the power supply to be in synchronization with the mains voltage, in order to maximize the real power drawn from the mains. In a perfect PFC circuit, the input current follows the input voltage as a pure resistor, without any input current harmonics.
What is a PFC converter?
Here we present a PFC converter which enables high frequency operation by maintaining soft switching and by using a control scheme which requires no current sensing. These advantages are verified with a prototype which achieves power factors above 0:996 (THD<10%) while maintaining ZVS across voltage and power for efficiencies 97%.
What are the benefits of a PFC converter?
While the primary benefit of a PFC converter is a high power factor and low THD, there are secondary benefits that the overall AC/DC power supply enjoys due to the inclusion of active PFC. Due to the high output voltage of the PFC stage, a moderate amount of energy can be stored in the PFC output capacitance.
What are the advantages of interleaved voltage-doubler boost PFC with coupled inductor?
However, the applications of the conventional boost structure are gradually limited as the output power demand is continuously increasing.In this paper, an interleaved voltage-doubler boost PFC with coupled inductor is proposed. It has the advantages of high efficiency, high power factor and low harmonics.
Can a grid-interface power converter improve the power density of PFC stages?
Overall, we expect the opportunities enabled by this converter to improve the power density of PFC stages and EMI filters for grid-interface power converters. One critical feature of the proposed converter is that the inductor current always returns to zero.
Does a PFC pre-regulator have inductor ripple current cancellation?
When the converter is operating at 2% and 100% duty cycle there is very little inductor ripple current cancellation. However, at these duty cycles the interleaved PFC pre-regulator has very little inductor ripple current.
