In this paper, a soft switching technique for a LED driver based on an Integrated Double Buck-Boost (IDBB) converter is presented. The converter is a two-stage cascaded Buck-Boost topology featuring a single main switch and positive voltage output. The first stage is connected to the grid and it is operated in discontinuous conduction mode (DCM); working this way, a high power factor is naturally achieved. The second stage is used to improve the dynamic performance of the LED current by working in continuous conduction mode (CCM), which allows a low output current ripple in a 69W LED lamp. As an integrated converter, the power losses of the two stages are concentrated in the single transistor, when hard switching is used. The proposed soft switching technique consists on a lossless voltage active snubber and a current passive snubber, which allows the converter switching at zero voltage at the turn off, and at zero current during the turn on. Simulation and experimental results are shown.
