Abstract :
The DC behavior of a clamped-mode, series-resonant converter is characterized systematically. Given a circuit operating condition, the converter´s model of operation is determined and various circuit parameters are calculated, such as average inductor current (load current), RMS inductor current, peak capacitor voltage, RMS switch currents, average diode currents, switch turn-on currents, and switch turn-off currents. Regions of operations are defined, and various circuit characteristics are defined to facilitate the converter design.<>
