Figure 2: Simscape Electrical based Boost Converter model

The circuit in the model is characterized by high frequency switching. The model uses a

sample time of 25 ns. The "Boost Converter" block used in the model is a variant

subsystem that implements 3 different versions of the converter dynamics. Double click

on the block to view these variants and their implementations. The model takes the duty

cycle value as its only input and produces three outputs - the inductor current, the load

current and the load voltage.

The model simulates slowly (when looking for changes in say 0 - 10 ms) owing to the high

frequency switching elements and small sample time.
