Magnetic Reset Circuit Design for Zero Induced Effects in Linear Transformer Applications

Magnetic reset circuit (MRC) is designed and applied in linear transformer.
Since the conventional transformer utilizes the concept of induced voltage current
from primary to secondary sides, magnetic reset circuit is designed so that both sides
of windings can be used effectively as voltage and current path without inducing any
current or voltage to respective windings. The objective in this project is to design
and simulate magnetic reset circuit using PSpice Schematics software. There are three
common techniques to reset magnetizing energy and this project only deal with one
technique only. All circuits in this project used tertiary winding as based circuit added
with MRC. In order to improve the capability of MRC, the clipper is added at
respective winding to remove unwanted signal, reduced time delay and smoother
output response. The expected outcome from this project is switching frequency 1
MHz with a maximum of 5 Ampere forward current are expected to successfully
operate in resonant gate driver (RGD)
