Abstract :
The power electronic transformer (PET) can perform the functions of voltage transformation, fault isolation, power flow regulation, reactive power compensation etc. This paper demonstrates the parameter design principles of capacitors and inductors in a power electronic transformer (PET) which based on modular multilevel converter (MMC) and input-series-output-parallel (ISOP) dual active bridges (DAB). The simulation results using PSIM software are illustrated to show the dynamic and static waveforms of the PET. And thermal simulation is carried out to verify that the IGBT in the DAB is soft switched.
