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.

The evaluation of power electronics has emerged since last few decades ago. The advancement in the power engineering has made many advantages as per cost, performance and size point of view. In recent years, the power electronics is used in many aspects of commercial, utility, military, transportation, aerospace, etc. A part of power electronics is DC-DC converter, and it has applicability in computers, spacecraft units, laptops, telecommunications and motor drives. The photovoltaic based energy generation is the modern way of generating the energy and is adopted all over the world. But the efficiency in power generation by the photovoltaic system varies with the climatic condition. To achieve better efficiency, DC-DC converter can be used. The technique called maximum power point tracking (MPPT) helps in efficiency optimization. This paper presents the survey over the existing energy optimization techniques; further efficiency optimization for future study is mentioned.
