Abstract
A new quadruples E-transformer made of ferrite is proposed in this paper. In order to control magnetic flux (w) in the ferrite with coil in the primary and secondary core transformer, wire coil should be twisted 50 with tiny air gap, resulting in higher efficiency. However, it should be suitable to heavy system loads. Otherwise, it will influence the duty cycle, and it will create ripple current for about 10 percents. The fixed air gap should be evaluated with respect to magneto motive (mmf), as one of their electromagnetic field sources in the system. In addition, the adjusted magnetic flux (w) also can be controlled by inserting air gaps, and the magnetic flux can be justified by varying the width of gap. In this experiment six air gaps are inserted in the quadruples E-transformer. The coil is composed of a ring wire gauge in which each ring wire gauge has radius r is 0.0004 m give the ripple current 0.036%. So the New quadruples E-transformer help greatly to make system more stable.
