This paper presents a comprehensive methodology for topology evaluation of bidirectional boost converters in electrified vehicle applications for higher power density. Based on the given specifications, major components in the converters are designed and sized, including the boost inductor, power module, and DC-link capacitor. 3D Finite Element Analysis (FEA) simulations are conducted to evaluate...
This paper presents the dynamic analysis of the interaction between an Interleaved Boost Converter with Coupled Inductor (DPCI) and a Constant Power Load (CPL). In order to perform the analysis, the analytical determination of the output impedance of the DPCI is presented, as well as the input impedance of CPL. Then, the same analysis is proposed for a conventional Boost Converter in order to compare...
Stray inductance of the DC bus in switching power converters causes transient overvoltages across the power devices, creating a need for higher rated, more costly switches. Moreover, EMI filters become necessary to mitigate the high frequency noise generated by the inductive loop of the busbar. In automotive applications, due to low cost and improved power density requirements, low inductance busbars...
