ABSTRACT 
It is well known fact that the power crisis faced in recent times is the major issue today. This situation leads to frequent load shedding and power failure. Needless to say that this has boosted the requirement of uninterrupted power supply requirement. Major chunk of the requirement is met using storage batteries and DC to AC Converters[4]. Presently 50Hz/230V power generation is met using transformer (magnetic core based on metals and metal alloys). However they are heavy in weight, bulky in Volume and gives rise to weighty boxes and overall much higher volume. Additionally metal transformer has inherent loss factor of about I0%.To overcome these problems high frequency ferrite based transformer less systems are used.Highvoltage highfrequency pulse power supply has been investigated for a long time and is largely industrialized at the fields of semiconductor manufacturing, packing, PCB and LCD panel manufacturing [15].The variable frequency inverters are used in wide applications especially three phase induction motor drive traction and it is popular in many high powers industrial applications such as speed and torque control.
