AN-1197Selecting Inductors for Buck Converters

Now, for a buck regulator, we can show that the duty cycle is: (5) where VD is the forward drop across the catch diode (≅0.5V for a Schottky diode). ‘r' can be finally written as: (6) and L is therefore: (7) where f is in Hz.

DC-DC Power Converters

The Cuk converter contains inductors in series with the converter input and output ports. The switch network alternately connects a capacitor to the input and output inductors. The conversion ratio M(D) is identical to that of the buck-boost converter. Hence, this converter also inverts the voltage polarity,

Introduction to Switch Mode Power Supplies (SMPS)

Buck DC to DC Converters The ideal output voltage for Buck converter is the product of the input voltage multiplied by the duty cycle of the transistor. By inspection, the output voltage will equal the input voltage if the transistor Q1 is always turned on. If Q1 is always off, then the output voltage will be zero.

Second-Stage LC Filter Design - Ridley Engineering

in this article shows three 2-kW converters. Two of them are mounted next to each other, and the third is shown on its side to reveal the hidden components. The main inductor is a large EE core, with a single bus bar through each window. These bus bars mount to the first capacitor, which is a low-ESR film type.

LM2576 - 3.0 A, 15 V, Step-Down Switching Regulator

inductors optimized for use with the LM2576 are offered by several different inductor manufacturers. Since the LM2576 converter is a switch−mode power supply, its efficiency is significantly higher in comparison with popular three−terminal linear regulators, especially with higher input voltages.
