ECE 464 Assignment 8: Boost Converter Circuit Analysis and Control, Assignments of Electrical and Electronics Engineering

University of Illinois - Urbana-ChampaignElectrical and Electronics Engineering

An optional assignment for ece 464 students, focusing on the analysis and control of a boost converter circuit. Students are required to simulate the startup of the circuit using given specifications, develop average value and linear models, design a controller for steady-state voltage tracking, and validate the design through simulation. The assignment is worth up to 25 points per problem.

Assignment 8 (OPTIONAL), ECE 464, FS 08 Name:__________________________
Due: Dec. 19, 2008; 12:00 PM READING: Chapter 15-16 Score:__________
This assignment is optional. It is worth up to 25 points per problem. It is not bonus. If
you turn in this assignment, your grade may increase, decrease, or stay about the same.
However, if you do well you can improve your grade.
8.1) Given a boost converter with a 100 uH inductor and 100 uF capacitor, simulate the
startup of the circuit. The input voltage is 10 V and the duty cycle is 0.5. Choose a
switching frequency so that the converter is in continuous mode from 1 W output to 20 W
output (resistive load). For the main switch, use an ideal switch in series with a 0.1-ohm
resistance. For the other switch, use a diode with an on-state voltage of about 0.7 V to
1.0 V. You can use PSPICE (there is an online free student version), Transsim (there is
a free version online), or any other circuit simulator.
8.2) Using the circuit in 8.1), develop the average value model based on state space
averaging. Simulate the startup of this circuit as well.
8.3) Using the model of 8.2), develop the linearized model of the circuit. Use output
voltage as the “output” and duty cycle as the “input.”
8.4) Using the linear model of 8.3), develop a controller that insures tracking of the
voltage to 20 V in the steady state. Show that the system is stable.
8.5) Using the controller of 8.4), simulate the circuit of 8.1) with the controller in place.
Show the output voltage converging to the correct value.
