2. abstract
• Pe is being used to maximize the
production and reliability
• APEI(interface) for RES
• How APEI improved eff of drives
and how and why it is used in
RES
3. introduction
• Renewable energy is trend but
still it is not applied to the level
of need
• main Problem of RESs is lower
efficiency but it can overcome
with APED techniques
•
4. intro - bases of ADPD (efficient and fast swich)
diode
gate turn of
thyristor
metal oxide semi conductor
field effect transistor
insulated gate bipolar transitor
integrated gate communcation transistor
5. intro - applications of PE
• Applications in:
• HVDC system
• static synchronous compensator
• DC and AC regulation
• DC/AC motor drives
7. introduction to APED
• rectifiers and invertors are built
using PE devices like IGBTs SCRs
with antiparellel diodes (rev I)
• Goal is to reduce conduction and
switching loses
• RES has 12-17 percent efficient
8. intro APED converter topologies
• flyback and pull back
convertor(old tech)
• buck, boost, buck boost, cuk,
Zsource converters and multi
level convertor (latest tech)
9. Application of APEI
• 60 % of elec consump
is of motors
• permanent magnets
motors and traditional
motors are also
affective now
• Electrical vehicles
