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 […]

Second V2G Workshop

Our Technical Partner Dr Charlie Elliott attended the second Cenex / Level Vehicle to Grid (V2G) workshop held in Nottingham on 6th February. It was a follow on event from the one in 2018 and it was great to see presentations on the outcome from real world installations abroad and in the UK. As last […]

Another sucessful project delivered!!

Our Technical Partner Dr. Charlie Elliott has just come back from Brazil where he sucessfully commissioned an ultra-compact high-efficiency motor-drive inverter based on SiC MOSFETs. This 15kW system hit 98% efficiency which is fairly special in it’s own right. If you then add the fact that the system has to work at 330 bar pressure […]

External ISO9001:2015 Audit Success

We had our first external audit of our ISO9001:2015 QMS by BSI since we made the 2008-2015 transition yesterday. I am pleased to announce that we passed with no issues at all, not even a minor non-conformance. Well done to all involved. Two “Opportunities for Improvement” were made that we will be taking on board […]

LCV 2018

Out Technical Partner Dr. Charlie Elliott decided to get in the spirit of things and take his own 30kWh Nissan Leaf to LCV this year. It wasn’t just for the free parking (although he has been in Yorkshire for over 30 years so something must have rubbed off by now) but also as a bit […]

3rd SiC MOSFET based project won!!

We are delighted to report that we have just kicked off another significant project using SiC MOSFETs. In the past 18 months we have been working on two SiC based motor drive systems. One is for an EV project where the attraction of SiC is the power density and part load efficiency benefits. The latter […]

More kit for the lab

We have recently made one of our most expensive equipment purchases in order to expand our validation testing capabilities and improve our efficiency. This is a bidirectional (source or sink) power supply that is capable of both AC and DC operation. This 30kVA / 800VDC / 510 V L-L unit also allows single or 3 […]
