Next Series of Power Electronics


T
here is growing concern about
environmental issues these days.
In the automotive industry, for
example, there has been a fo-
cused effort towards developing the hy-
brid electric vehicle (HEV) and electric
vehicle (EV). In the meantime, more func-
tions are being operated by electronics
while the technology trend for in-vehicle
electronics has changed significantly.
Specifically, the development of advanced Fig. 2: Heat generation comparison of various capacitors
