Role of Power Electronics
The power electronics interface
facilitates the transfer of power
from the source to the load by
converting voltages and currents
from one form to another, in which
it is possible for the source and
load to reverse roles. The controller
shown in Fig. allows management
of the power transfer process in
which the conversion of voltages
and currents should be achieved
with high energy-efficiency and
high power density.

National Perspective
Strengths
• Strong academic base and R&D expertise to generate cost
effective designs
• Strong system engineering and application knowledge
within the India Industry
Weakness
• Lack of R&D funding by industries
• Negligible manufacturing base for the key components in
power electronics
• Low level of interaction between the industries, R&D and
academics
