Tools, Methods and Quality Approaches to Deliver High Quality Control in Digital Power Electronics

​RT Spotlight San Francisco - The key reasons for using digital control in power electronics are:

- Lower cost

- Complex control requirements

- Configurability

- Optimizing for operating point variation

- Control adaption

- Management of the non-linearity of the converter

- The ability to tune the switching times precisely to minimize the power loss and maximize the efficiency.

The advantages of digital control of power electronics bring with them challenges. Dealing with these challenges before they expose problems is the key to fast product delivery and reliable and robust operation.

The challenges include:

- Limited Number of Bits

- Sampling and limited bandwidth

- Processing Delay

- Producing and maintaining high quality software code

The presentation explores the detail of these challenges and presents tools, methods and quality approaches to address them.
