Abstract

The data center industry is headed towards a lower point of load voltages with increased load demands contributing to higher I2R losses in power busses. Raising the bus voltage from 12V to 48V is a popular area investigated today for reducing power delivery losses. Switched capacitive converters (SCCs) are a popular topology used for this purpose. However, SCCs suffer from low tolerance for operating conditions and are unregulated. The proposed multi resonant switched capacitor buck converter (MRSCBC) can resolve these challenges while also providing output regulation. Switch mode power supplies exhibit high electromagnetic noise and with an increased number of switches in an MRSCBC, controlling EMI noise and compatibility is essential. This thesis will focus on the use of PCB design and software simulations to optimize electromagnetic interference (EMI) and parasitic elements in the traces to improve the robustness of an MRSCBC.
