Abstract :
This paper extended the research on the system-level safe operation area (SSOA) of power electronic converters in our previous literatures, which proposed a comprehensive procedure of constructing SSOA, investigated the impact of the microscopic transient processes and macroscopic control algorithms, and pictured the SSOA of a battery charger for plug-in hybrid electric vehicles. The genetic algorithm is used to optimize the system parameters at the macroscopic level. More importantly, thermal characteristics of the MOSFETs and battery impedance are enclosed to enhance the system reliability and maximize the power capability. In the end, the SSOA for a SiC JFET based electric charger is also discussed.
