2. Power Electronics Converters
 A power converter is an electrical or electro-mechanical device for converting electrical energy. It may be converting AC to or from DC, or the voltage or frequency, or some combination of these.
Give a brief overview of the presentation. Describe the major focus of the presentation and why it is important.
Introduce each of the major topics.
To provide a road map for the audience, you can repeat this Overview slide throughout the presentation, highlighting the particular topic you will discuss next.

3. Types of Power Converters
It is broadly classified into six types such as
Diode Rectifiers
AC-DC Converters
DC-DC Converters
DC-AC Converters
AC-AC Converters
Static Switches

4. Diode Rectifiers It converts AC input into fixed DC voltage
Input may be Single-phase/ Three-phase

5. AC-DC Converters
It converts the constant AC voltage to variable DC output voltage.
It mainly uses SCR’s.
Applications: DC drives, metallurgical etc..

6. DC-DC Converters Also known as DC Choppers
It converts fixed DC i/p voltage into a controllable DC o/p voltage
Applications: Subway cars, trolley trucks, DC drives

7. DC-AC Converters
It converts fixed DC voltage to a variable AC voltage.
O/p maybe a variable voltage/frequency.
Applications: Speed control of induction motor, UPS, HVDC transmission

8. AC-AC Converters
It converts fixed AC i/p voltage into variable AC o/p voltage
They are of two types:
AC regulators
It converts fixed AC voltage directly to a variable AC voltage at the same frequency
Applications: Speed control of fans and pumps

9. 2) Cycloconverters:
It converts i/p power at one frequency to o/p power at a different frequency through one stage conversion.
Applications: In slow speed large AC drives like rotary kilns

10. Static Switches
It possess many advantages over mechanical and electromechanical circuit breakers.
Dependency upon the input supply, the switches are called AC static switches/ DC static switches.
