Vibration energy harvesting with piezoelectric materials currently generate up to 300 microwatts per cm2, using it to be mooted as an appropriate method of energy harvesting for powering low-power electronics. One of the important problems in bimorph piezoelectric energy harvesting is the generation of the highest power with the lowest weight. In this paper the effect of the shape and geometry ...

The emergence of silicon carbide(SiC-) based power semiconductor switches, with their superior features compared with silicon(Si-) based switches, has resulted in substantial improvement in the performance of power electronics converter systems. These systems with SiC power devices have the qualities of being more compact, lighter, and more efficient; thus, they are ideal for high-voltage power...

Acknowledgment First of all, I would like to thank my parents who raise me and support me to do further study in Norway. I appreciate the help from my supervisor Lars Einar Norum and Phd student Hamed Nademi. I benefit a lot from their meticulous attitude to study, abundant knowledge and minded guidance. I am very grateful that NTNU Department of Electric Power Engineering provides very good ha...
