Closed Loop Interleaved Boost PFC Design in z-Domain

In this webinar, we design an interleaved boost PFC, close two independent inner current loops with digital controllers, and design an outer voltage loop to provide the current reference for the inner loops. The system is being set up for embedded code generation with SimCoder and then we verify the operation with a Typhoon-HIL real-time simulation.

Topic covered:

- open loop frequency analysis

- inner current loop design

- interaction between interleaved paths and impact on the current loop

- outer loop frequency sweep with working interleaved current loops

- input impedance sweep

- use of scripting to automate the verification of various operating scenarios

- setup for embedded code generation

- verification of the design with real-time simulation on the Typhoon-HIL system
