The total income in the quarter under review rose to Rs 19,215 crore from Rs 18,441.72 crore in the year-ago period. Power Finance Corporation (PFC) on Friday posted a nearly 24 per cent rise in its consolidated net profit to Rs 4,893.91 crore for the December quarter, mai...
CVFF + 2p 1 RVFF fP ^ 2.2 mF (15) This results in a single-pole filter, which adequately attenuates the harmonic distortion and provides power limiting. The RMOUT resistor is sized to provide power limiting for the circuit. The power limit is set to 140% of the maximum output power. ...
AUGUST 2024 230-V, 3.5-kW PFC With >98% Efficiency, Optimized for BOM and Size Submit Document Feedback Reference Design Copyright © 2024 Texas Instruments Incorporated 5 System Overview www.ti.com A typical value of 47kΩ for the FREQ resistor results in a switching frequency of 44kHz....
A 10kHz interrupt is set in the firmware and the PI control loop is adopted for voltage loop in the design. Because PFC output voltage has two times the line frequency voltage ripple, which results in a third harmonic current, the voltage loop’s bandwidth needs be kept low enough to mini...
proper losses of the Si SJ MOSFET Q1 during turn-on. If this pulse falls short, the possibility to have severe hard commutation is high in the Si SJ MOSFET, which would produce destructive results if it occurs during long periods. Similarly, the LV MOSFET could run continuously in avalanche...

This method gives a good starting point for any design, but a final design requires an iterative approach combining the FHA results, circuit simulation and hardware testing. An alternative design approach is given in TI Application Note, LLC Design for UCC29950, Texas Instruments Literature Number ...
