What We Mean by Power Electronics?

Uses semiconductor devices as switches for power

conversion from one type of source to another.

Applies control techniques in order to obtain the desired

input and output requirements.

We can say that Power Electronics combine Power,

Electronics and Control.

Thus we can define Power Electronics as the applications

of solid-state electronics for the control and conversion of

electric power. Rashid M. (2001)

Power Input:

from electric utility, 1 or 3 phase, 50 or 60 Hz: ac input

from dc supply/battery: dc input

from previous converter output: ac/dc input

Power Output: to load (load can be of R or L or R-L nature)

output parameters: dc/ac voltage, dc/ac current, frequency & number

of phase

Power Converter Core : Using

BJT/ MOSFET/ SCR/ GTO/ IGBT/ MCT as switch,

Diode, L and C as energy manipulators

Because converter core used switches, the electronic circuits are

also called Switch-mode Power Supplies

Apakah electronic switching itu ?

(1) Power Diode

(2) Silicon-Controlled Rectifier (SCR) or Thyristor

(3) Gate Turn-off Thyristor (GTO)

(4) Power Bipolar Junction Transistor (Power BJT)

(5) Power Metal-Oxide Field-Effect Transistor (Power

MOSFET)

(6) Insulated-Gate Bipolar Transistor (IGBT)

(7) Mos-Controlled Thyristor (MCT)

As electronic switching, there is two conditions, ie. ON and OFF
