In this tutorial, we are going to learn about simple tutorial of power electronics.
Power Electronics – Power Electronics deals with how to control and convert power (electric energy) into one form to another and how to utilization of power at high efficiency.
- Below is the distribution of Power Electronics:
- Power – Generation, Transmission, Distribution.
- Electronics – Solid State Device, Electronics Circuit, Signal Process.
- Control – Steady State Characteristics, Dynamic Characteristics.
- Power generation – For Power Generation basically we use below are the process:
- Fossil Fuel
- Nuclear Energy
- Renewable Energy
- Below are the Main Power Electronics Components:
- Thyristor
- Diac
- SCR
- LASCR
- Traic
- UJT
- IGBT
- GTO
- Power Electronics Circuit can be classified into different category which is depending on input and output.
- Rectifier – It is convert AC into DC is called rectifier, It is basically used in battery charger, excitation system of synchronous machines.
- Chopper – It is used for D.C. to D.C. converter which is use in D.C. Drives, Battery Driven vehicles etc.
- AC Voltage Regulators – This is use for AC to AC control and its useful for speed control fans and power pumps.
- Cyclo Converter – It is use for control of slow speed large AC drive.
- Inverter – It is convert DC into AC and it is use in heating induction, UPS, HVDC, wind and solar energy.
- Below are the Power Components which are use in power circuit.
- Power Diode
- Power Transistor
- Power Mosfet
- Power IGBT
- Chopper
- Power Electronic Circuit :
- AC to DC = Rectifier
- DC to DC = Chopper
- AC to AC = AC Chopper
- DC to AC = Inverter
- Uncontrolled – Diode
- Semi Controlled – SCR
- Fully Control – Both ON & OFF are controlled
- Power Circuit Required :
- Power Rating
- Frequency of operating
- Cost and size reduction
