CogniPower Evaluation Boards Allow Predictive Energy Balancing Control of Flyback Converters

Evaluation boards for CogniPower Predictive Energy Balancing Control of flyback converters are now available. The dynamic response displayed is described as near ideal, and the power output is harmonically pure. The company says the need to make trade-offs between stability and agility is eliminated. This power converter is said to have both intrinsic stability and excellent transient response. It responds to load changes in a single cycle without overshoot or undershoot or compensation.

According to Thomas Lawson, Founder and President of CogniPower, "The additional circuitry required to achieve this dramatic improvement in responsiveness amounts to little more than a half a dozen transistors and a few resistors. The technology can be folded into generalized power management chips without adding significant cost or complexity."

For the evaluation boards, the input voltage is a AA battery. The output is 5Vdc. Circuitry to generate a dynamic load is included to exercise the system. Full operation and smooth start up are guaranteed to below one volt on the battery. The evaluation board can be used, for example, to generate an extremely well-regulated 5 volt supply in a system lacking quiet power supplies.
