This three day lab based design workshop, sponsored by Biricha Digital Power, will teach you how to reduce your development time of digital power supplies. During the workshop, you will design and code multiple closed loop digital converters and receive the necessary templates, libraries and skill to implement multiple converters with minimal coding. Based on Texas Instruments' C2000 family of microcontrollers, the course is aimed at Analog PSU Designers and embedded systems engineers who need to design high performance digital power supplies.
Workshop Outline
Typically the morning session is dedicated to the study of the theory and principles, whilst the afternoon session focuses on laboratory exercises to consolidate the theory.
In addition, all attendees will receive a copy of Biricha Digital Power Ltd's Digital Power Library. This library is a collection of software functions written specifically for the C2000 family of processors including Piccolo A, Piccolo B+CLA and the 28335 floating point in order to reduce the programming burden of the digital power supply designer.
These functions allow quick programming of the device peripherals (such as PWM and ADC setup) and are written in such a way so as to make programming easy and intuitive.
