High Efficiency Topologies for Dual Voltage Inputs
… In this thesis, a novel new solution, named the “Dual Range” (or Dual Voltage), is introduced and explored. The solution suggested is mainly attractive for high-efficiency Universal Mains power supplies by providing a smaller dynamic operating range in Universal Mains. The result is a reduction of …

Fusing strategies for the dual-voltage fault
This thesis focuses on the 42V - 14V fault in a dual voltage system and discusses the possibility of effective fusing. A simple model for the system had been created from technical documentation. Based on the model and the goal of achieving a stable state through fusing, constraints are set on the …
