—Solid state transformers (SSTs) have lower physical profiles than traditional 60 Hz transformers and provide active control of power flow. However, they are not as efficient as traditional 60 Hz transformers because of the presence of power electronic converters. This work presents an analytical loss calculation model of an SST. It evaluates conduction(More)
Power analysis attacks explore the encrypted information by monitoring the power traces of physical crypto-systems. Among all published power analysis attacks, correlation power analysis (CPA) is the most effective attack that has been reviewed by many researchers recently. Meanwhile, various countermeasures have been proposed to against CPA attacks. In(More)
