Electric vehicles (EVs) use a high-voltage to low-voltage DC/DC converter (Auxiliary Power Module, APM) to power auxiliary loads. It is typical to operate low-voltage systems at 12 volts from 400V or 800V battery. Aside from this, the industry is pushing the power limits of the DC/DC converter to meet the needs of the new components (sensors etc.) being added to the electric vehicles. A Phase-Shifted Full-Bridge (PSFB) based DC/DC converter is the most preferred topology for this application. As part of this work, various popular PSFB topologies are investigated to determine. the most suitable converter for the APM application. An in-depth topological analysis is conducted. in order to understand the pros and cons of each version of PSFB. To determine the most effective PSFB converter, different PSFB converters are designed, and component-wise power loss analysis is carried out.
