Buck Converter Critical Inductance Interactive Tool

% Buck converter critical inductance interactive tool assist user to
% determine the critical inductor value for buck converter design. The
% critical inductance determine the Boundary Conduction Mode (BCM) of a
% buck converter.
% The critical inductance versus switching frequency characteristic curve
% is computes based on the desire buck converter output voltage and current.
% User can adjust the duty cycle using the slider to see how the duty cycle
% affects the critical inductance characteristic curve.
