Recom free ac-dc PSU book is good

Written by the firm’s technical director Steve Roberts, it is called ‘AC/DC Book of Knowledge’.

Electronics Weekly spent a while looking through it, and gives it a thumbs up.

Not only a good introduction to topologies for PFC, power and control, but goes into the next level of detail on many topics – there is a particularly good section on driving the gates of GaN power transistors.

Perhaps not surprisingly for a maker of small isolated dc-dc converters, the use of small isolated dc-dc converters is advocated in many power transistor gate drive circuit diagrams, but the text justifies their inclusion as problems solvers – justified particularly well in section on driving the notoriously fragile gates of GaN HEMTs.

The book is a partner to Recom’s ‘DC/DC Book of Knowledge’, also by Roberts, published in December 2014 – 15,000 copies have been distributed globally.

“The DC/DC Book of Knowledge has been so well received in the industrial and educational communities that I felt obliged to write a companion AC/DC book,” he said. “The two books together now cover many of the fundamental topics of power supply development.”

The AC/DC book has 12 chapters covering subjects including:

“These topics have been chosen so that they do not overlap with the chapters in the DC/DC book so that both books reinforce each other rather than being repetitive,” said Recom.

Although the book is free to download in pdf format, you will have to give Recom your contact details. In this case, it is probably worth the sacrifice.

Roberts will be handing out copies of the book in Hall A5 (stand 210) at Electronica and is available to sharing electronics knowledge with students and engineers there, said Recom.
