Acerca de este curso: Learners will design a DC-DC converter that powers USB-C devices (20 V at 3 A) from a dc input voltage source such as a lithium-ion battery pack or a desktop computer power bus. Aspects of the project will include: ● Design of converter power stage and magnetics. Requires mastery of courses 1, 2, and 5. ● Simulation to verify correct steady-state operation. Requires mastery of courses 1, 2 and 4. ● Design of converter control system. Requires mastery of courses 3 and 4. ● Simulation to verify correct control system operation. Requires mastery of courses 3 and 4. ● Preparation of milestone reports documenting the design and its performance The reports will be peer graded.
Para quién es esta clase: This course is primarily aimed at professional electrical engineers or electrical engineering graduate students, who need to design or understand switching regulator systems.

SEMANA 3
Preliminary Controller Design
Develop an averaged model of your power converter. Select a control approach (voltage mode, peak current mode, or average current mode control), and begin the design of the control loop(s) to meet requirements on crossover frequency and maximum closed-loop output impedance. Begin development of LTspice averaged simulation of your controller design.

SEMANA 6
Complete Design and Documentation
Complete development of an LTspice switching model of your closed-loop converter system, and verify that your system meets load current transient requirements. Complete the addition of current limiting to your circuit, to prevent inductor saturation during transients. Demonstrate your final design, including: operation at the specified operating points, closed-loop response to a step change in load current, current limiting, inductor and capacitor size, and efficiency. Document the final design for submission to Milestone 3.

This was an amazing course. I am almost sad it's over.
The very best teachers and fellow learners.
Great job COURSERA and University of Colorado Boulder
very good practice of designing a dc/dc converter, you choose the topology, select components based on what you have learned. Some previous experience with PMIC would make you understand much better. Thanks for the UC Boulder team and whoever contributes in developing this course and provide help in discussion forum!

I cannot recommend this course as well as the whole specialization enough. Absolute value for the money spent.
