We describe a single-stage low-cost and efficient fuel-cell (FC) power-electronics system (PES), which comprises a front end phase-shifted high-frequency (HF) full-bridge inverter followed by a step-up high-frequency transformer and a forced cycloconverter for universal residential FC power system (i.e., 110 V/240 V and 60/50 Hz). This single-stage dc/ac converter approach meets the higher energy...
The cold cathode fluorescent lamps are particularly used in back lighting of LCD monitors. The supplying circuits must have the characteristic of good thermal management in order to avoid temperature rise over 60 degC, which can cause large dark spots in the screen. In this paper an innovative solution is proposed that consists on a Royer configuration of a current-fed push-pull inverter supplied...
