The document presents a seminar on the design of a solar-powered three-phase motor, integrating components such as photovoltaic cells, DC-DC converters, and inverters. It discusses the functionality of each component and highlights the advantages of using current-fed converters for controlled DC output. The aim is to use solar energy to power a three-phase electric motor for various applications, such as water pumping.

• Photovoltaic is the direct conversion of light into
electricity at the atomic level.
• A photovoltaic cell(PV) is a device that converts sun light
into direct current through photoelectric effect.
• Photovoltaic cells are made of semiconductor devices.

8. DC- DC CONVERTOR
• DC- DC Convertors used for the
purpose to a get a controlled DC
output . It converts the
uncontrolled DC to controlled DC.
• The convertor used is current -
fed type:-
 current –fed push pull convertor.
 current – fed power convertor.

9. ADVANTAGES OF CURRENT-
FED CONVERTORS
• No fast rising current spikes created.
• Do not causes magnetic core
saturation under erroneous
condition.
• As SCR based power supply i.e. it is
more robust

10. • Controlled output DC is obtained
• No need of filter capacitor at input
• This topology can also be derived from
boost convertors by inserting a
transformer.

13. INVERTER
• Power electronic device which convert
DC to AC.
• Three phase six pulse inverter used.
• A power inverter can be entirely
electronic or may be a combination of
mechanical effects.
• Inversion is done by the help of
transistors.

18. CONCLUSION
The DC power so obtained from solar power
photovoltaic cell is fed to CFPP converter
and controlled DC so obtained is inverted
by three phase six pulse inverter in order to
integrate three phase electric motor for
various applications.
