The increased power consumption and power density demands of modern technologies combined with the focus on global energy savings have increased the demands on DC/DC power supplies. DC/DC converters are ubiquitous in everyday life, found in products ranging from small handheld electronics requiring a few watts to warehouse sized server farms demanding over 50 megawatts. To improve efficiency and power density while reducing complexity and cost the modular building block approach is gaining popularity. These modular building blocks replace individually designed specialty power supplies, providing instead an optimized complete solution. To meet the demands for lower loss and higher power density, higher efficiency and higher frequency must be targeted in future designs. The objective of this dissertation is to explore and propose methods to improve the power density and performance of point of load modules ranging from 10 to 600W.
