— This project discusses a half bridge converter with four independent outputs for a plasma display panel application. The outputs are typically 180V/350W, 65V/200W, 19V/15W, 17V/10W. Two MOSFET switches in a single leg constituting a half bridge generate a rectangular voltage. The output is connected to the primary of a transformer, which has four secondaries. All outputs are regulated through the amplitudes of carrier and sinusoidal reference waveforms respectively. The outputs are regulated independently over a wide range by varying the amplitude of the reference waveforms used. The simulation of this converter has been and the results closely match with the expected values. Cross regulation was also found to be minimal.
