99% PFC Efficiency – with Silicon at Low Cost!

Power factor correction ("PFC") functionality is a fundamental building block in all midrange power supplies for electronic equipment. Our work primarily relates to power levels from about 300W - below which efficiency rarely gets commercially rewarded - through to 3kW, which corresponds approximately to the limit for practical singley phase operation. So - we are optimising cost and performance in applications such as servers, on-board chargers, industrial and medical power converters, etc through a new generation of control and driver devices. Many of the techniques discussed have parallel deployments in DCAC and general energy management.
