The study of physical phenomena basic to electronics, such as discharges, thermionic and field emission, and conduction in semiconductors and metals. Physical Electronics deals with the actual phenomenon occurring within the device during its operation. However, in the part of electronics, we study how an electronic device actually works. On the other hand, electronic engineering is the application part of core electronics and under this section, we deal with successive development. Finally electronics can be defined as "the field of science and engineering which deals with electronic devices and its utilization". The journal list includes different branches of electronics like power electronic, marine electronics, bioelectronics, etc. Power electronics is one of the dynamic technologies, which is an application of convert and control of electrical power. Power electronics research has been transformed from developed countries to developing countries. The recent advances of power electronics is renewable energy sources. Power electronics has a lead role in the electronics engineering journals list.
