This study proposes an analytical solution for the inductor current of the BOOST converter using the relative inductance as an independent variable based on the relative variable method. First, the expressions of the actual and relative values of current...
Thank you very much for the response These are the equations I have used to compute for my RLC and duty cycle to be in CCM. Sorry that I forgot to mention that my boost converter is operating in CCM. Below are the provided Transient Response of the Inductor current with the PWM. I...
This converter further increases the voltage gain and reduces the voltage stress of the power device.Using magnetic integration technology, two inductors are wound on the same magnetic core to form coupled inductor, which improves the power density of the converter.Finally, the basic working ...
Boost Converter Solution / ALPS 1 Introduction Traditionally, the inductor value of a boost converter is selected through the inductor current ripple. The average input current IL(DC_MAX) of the inductor is calculated using Equation 1. Then the inductance can be calculated using Equation 2. It ...

A boost converter is a DC/DC power converter which steps up voltage from its input (source) to its output (load). In continuous conduction mode (current through the inductor never falls to zero), the theoretical transfer function of the boost converter is: ...
While performing the analysis of the Boost converter, we have to keep in mind that The inductor current is continuous and this is made possible by selecting an appropriate value of L. The inductor current in steady state rises from a value with a positive slope to a maximum value during the...
Typical White LED Backlight Driver Boost Converter 1 Inductor Requirements TI's LCD backlight boost converters specify an inductor within a certain nominal value, or within a range of inductor values. This intended range accounts for inductor tolerances and some variation in inductance with current....
