Activity Code

4G.026

Objectives

To conduct a system level concept analysis to make sure the DC/DC concept fits the most common product needs.
To explore the possibilities and drawbacks with digital controlled DC/DC converters
To explore potential from new technologies such as GaN devices
To design and test a bread board to evaluate the performance

Challenges

To implement digital control “from scratch” and make it a competitive alternative to traditional analog control.

Benefits

Improved converter efficiency and very flexible to adjust for different applications including software programming properties without changing the hardware.

Features

Features are for example to implement adaptive delay control in the timing when using synchronous rectification, programmable start up-/shut down behaviour and the possibility to adjust traditional analog regulation parameters “on the fly” by means of adjusting the software without making any changes in the hardware.

System Architecture

The architecture consists of a centralized microcontroller that controls three independent DC/DC-converter simultaneously.

Plan

First step is a conceptual design to be specified and defined.
Second step is to have a BB design Review.
Third step is to complete all tests and relevant analysis as input to the final review

Current status

The project is completed
