Synchronization and Delay Techniques for Driving lMHz Totem-Poled Power MOSFET Configuration

This project discusses about the synchronization and delay techniques that
are suitable for totem-poled power MOSFET configuration operating at high
speed. Modification has been made to the proposed synchronization circuit fur
earlier PWM controllers that have an operating frequency ranging from 80 kHz to
120 kHz. Experimentation is carried out to obtain the most suitable means in
synchronizing the PWM signals and adding delay function. The synchronization
and delay network is able to operate at high switching frequency of 1 MHz. In
addition, two different sets of complementary square-wave are achieved at duty
cycle of 50 % and 20 %. The result with 20 % duty cycle can be used for
previous work in investigation of high frequency effects on soft switch-switched
synchronous rectifier buck converter
