Abstract :
In designing switch mode power supply (SMPS), the desirable feature is to have an efficient and compact design. The main idea is to increase the switching frequency and reduce the bulky magnetic parts of the converter. This leads to a compact size, less weight, reduced cost and increased power density of the converter. This paper presents a high frequency full bridge DC to DC converter, using a multilayer coreless printed circuit board (PCB) step-up power transformer. The converter was simulated and also implemented on the PCB. The pulse width modulated (PWM) signals were generated, using a microcontroller, to switch the Metal oxide semiconductor field effect transistor (MOSFET). The design of the converter is tested up to the power levels of 5 Watts with the switching frequency in 2 to 3MHz range. The energy efficiency of the converter is 74.86% at 2.4 MHz.
