A buck-boost topology operating in discontinuous conduction mode (DCM) is used as an off line LED driver for lighting applications. Operating from a full wave rectified ac-voltage with minimum input ...

Bogdan Micea] uses a laptop cooler, but was a bit annoyed that his cooler would run at the same power no matter how hard the laptop was working. Rather than keep adjusting the cooler’s power ...

In this paper, a single-stage LED driver is proposed for a street lighting system. Two boost circuits that share a single inductor are formed by integrating the switches of a half-bridge LLC resonant ...
