Digital control provides
novel switcher design
GSPK Design has developed innovative switch-mode power solutions using DSP-based digital control techniques
The company's main focus has been developing highly cost effective implementations of digital control methods that challenge analogue techniques on both cost and performance. Basing the solutions on TI's high performance, low cost C24x DSP has played a significant part in enabling GSPK's power solutions to meet their demanding goals.

Manufacturable design moves to full production
GSPK Design has successfully assisted in the design and development of a revolutionary new electronic tape measure, and is now manufacturing the device
Said GSPK Design's Technical Director, Mike Kinghorn: "Digital control opens up many advantages over the traditionally used analogue techniques.
As well as improving the overall control performance we can dynamically optimise switching timing to gain improved efficiency.
There is also major cost advantage if your application requires a microcontroller because the TI DSP can perform both switch-mode and application control functions".
The company is already designing the technology into products for major switch-mode power users.
It has applied the techniques to develop a power convertor which conforms to the IEC61000-3-2 Limits for Harmonic Current Emissions Standard without needing a separate switching stage for power factor correction.
This has obvious cost benefits in suitable applications.
This technology offering is set to enhance GSPK Design's already unique electronic design reputation within the market.
The principle aim is to help those companies currently developing power electronics using analogue methods to gain the benefits of using digital control.
Jean-Claude Soroka, TI's European C2000 Business Manager said "Combined with GSPK's design expertise in power supply systems, TI's highly integrated C2000 DSP platform provides unique advantages for SMPS and UPS customers looking for the best performance at the cheapest price.
GSPK has a highly innovative solution in switch-mode power and we are very pleased to have them as a member of our third party network".
In partnership with Durham University, GSPK Design has committed to a three year research programme to further exploit the benefits of the new technology.
