Compound Semiconductor Application Catapult Visit

Our Technical Partner (Dr. Charlie Elliott) visited the Compound Semiconductor Application Catapult in Newport last week. He commented that is was great to see the fantastic team and facilities that are rapidly being established there. We are very much looking forward to working with them on future projects and already have a perfect application that […]

High torque motor drive system testing

Two of our Principal Engineers have just come back from being on site at Newcastle University School of Electronic and Electrical Engineering. They were utilising the excellent dynamometer facilities that are installed there. The motor under test was a high pole-count (66!) permanent magnet type which is controlled by a bespoke high-reliability and rugged inverter […]

Traction Power Converters Shipped

SPS has just completed supplying the first batch of traction power converters used by Clayton Equipment in their innovative full-electric and hybrid locomotives. They are rated at up to 180 kW and suitable for use at up to 750 V DC (max) with IP68 rating. Specific steps have been taken with the design to ensure […]

Succesful External ISO9001 Audit

Today was our annual external audit by BSI for our ISO9001:2015 quality management system. I am pleased to report that we passed with flying colours with no non-conformities at all. We did have an interesting discussion with our auditor on the subject of collaborative working. For certain this is the manner in which we prefer […]

EV SiC-based Inverter Project Update

SPS has just started testing the latest version of the highly challenging PCB it has designed for an automotive SiC-based EV inverter. The PCB not only implements all the required gate drive but integrates many other essential sensing and other auxiliary features to ensure electrical and functional safety. The space available for the PCB is […]

Innovate UK Project a Success!!

SPS has now completed the IUK funded project with it’s long term customer Ceres Power that began in July 2017. SPS’s part of the project was associated with a low-cost 1kW isolated DC to AC grid tied inverter system for use on Fuel Cell based micro combined heat and power residential applications. SPS’s two main […]

Functional Safety

The control of electrical power is fundamental to what SPS does and has inevitable safety implications not just in its raw form but also in terms of what it allows you to do to effect motion etc. It is something that SPS takes very seriously in all aspects of what it does to protect its […]

June is Training Month at SPS

Not quite sure why it has worked out like this but June seems to be the month for Training this year. First of all one of our Principal Engineers (Peter Moriarty) went on a 4 day course run by Ridley Engineering on Power Supply Design. This is a world reneowned course run by one of […]

PCIM 2019

May in Nuremberg – must be time for PCIM again!! This year as well as our Technical Partner Dr. Charlie Elliott, our Production and Quality Manager Alan Yarker also attended. Sadly no sitting outside drinking cold beers this year and thanks to KLM it was a bit of a truncated visit but still well worth […]

Stephenson Challenge / Driving the Electric Revolution

Our Technical Partner Dr. Charlie Elliot has been involved in this cross industry initiative for quite some time as it originated in Power Electronics UK. He recently attended a key update meeting in Birmingham. A detailed video giving more details can be found here. Subject to business case and match funding from industry, government has […]
