สิ่งจำเป็น Abstract—Power electronics enables the efficient generation,
use, and distribution of electrical energy because it substantially
improves energy conversion efficiency. In order to realize the large
electrical energy savings potential enabled by power electronics
suitable technological solutions at acceptable cost levels are needed.
Moreover, public policy and public acceptance must play an increasingly
important role. An effective way to quantify the value
of power electronics is needed and it must be presented in such
a way that it is understood and appreciated by policymakers. In
this paper, energy payback time is shown to be a powerful tool
for weighing the value of energy savings achieved by using power
electronics versus the energy needed to manufacture the systems.
A life cycle analysis of two power electronic converters and their
parts is performed. The benefits of energy savings versus energy
invested in manufacturing and end-of-life management of power
converters is analyzed. It is shown that power electronics systems
have considerably shorter energy payback time compared to other
technologies.
