99% PFC Efficiency – with Silicon at Low Cost!

Power factor correction (“PFC”) functionality is a fundamental building block in all mid-range 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 single phase operation. So – we are optimizing 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 DC-AC and general energy management. Get the full article on or view it here.
