POWER ELECTRONICS BASIC COMPONENTS INTRODUCTION PART 1

2. Special branch of Electronics Engineering in which
ratings of components will be much higher may
be in hundred Amperes or thousand voltages
EASY ENGINEERING

3.  Smaller current &
voltage
 Deals with small
components
 Generally up to very low
voltage say 40V
 Deals with very big
amount of current &
voltage
 Big components
 Threat to life so more
protection required
EASY ENGINEERING

4.  Carry information
 or control signal
 Transmits power
EASY ENGINEERING

5.  1. AC TO DC (Rectifier)
EASY ENGINEERING

6. 2. DC TO AC (Inverter)
Converts DC to AC
Mostly used with Solar power generators
