Nowadays there are various types of power electronics converters available, most of them are used to convert battery with 12 V or higher.This thesis discusses and analyses the simulation and implementation of converter module for lower voltage/ high current (3.7V/50A) Lithium battery. The converter module consist of three major subsystems: full bridge H layout circuit that comprise of four switches to convert the unidirectional flow of current to the periodically reverse one, gate driver circuit for controlling the switching mode for the MOSFETs and the Arduino due module that  is used as pulse width modulation (PWM) to control output and the switching frequencies. Different semiconductors and passive devices such as MOSFETs, diodes, capacitors and resistors were chosen and used in construction of converter and discrete gate driver. Converter model was created and examined using Simulink and the devices’ spice model and parameters provided from electronics devices manufactures. The results focused on many aspects such as circuit efficiency, power MOSFETs losses and its critical performance metrics, such as dI/dt or peak drain voltage overshoot/undershoot.The circuits implementation was done on a Printed Circuit Boards.
