%% Parameters for DC-DC Converter Model Fidelity Comparison example

% This example shows how to use different levels of fidelity in DC-DC 
% converters. The system contains three buck-boost converters. The top 
% converter uses an ideal switch at a sample time of 10 us. To yield 
% accurate results even though the model is under sampled at a sample 
% time of 50 us, the middle converter uses an averaged switch with 
% averaged pulse. To further increase the sample rate and to operate as 
% an ideal averaged converter, the bottom converter uses an averaged 
% switch and duty cycle instead of gate pulse. The Control subsystem 
% contains a PWM generator. The Scopes subsystem contains Scope blocks 
% that allow you to see the simulation results.
