Abstract

An AC/DC converter for outputting high current, low voltage output from a high frequency AC source is described. The AC/DC converter includes two resonant components, a resonant circuit having a capacitor and an inductor. Both of the resonant components are connected in series and form a series resonant circuit. The converter further includes a transformer having a primary winding with a center tap to a secondary winding. The resonant circuit and the primary winding are connected in series. The center tap is connected to an output filter and a load, while the other two ends of the secondary winding are connected to two controlled switches, respectively. A drain of each of the two controlled switches is connected to opposite ends of the secondary winding, while each of the sources of the two controlled switches are interconnected. Two anti-parallel diodes are respectively connected across the two controlled switches. Two capacitors are also respectively connected across the two controlled switches. The on-time of the controlled switches is regulated to control the output voltage of the converter. The advantage is an inexpensive converter adapted to output high currents at low voltages with very little ripple and very low slew rate.
