# Introduction to Power Processing
--

## Fundamental Block Diagram

---
# Different Source Voltage Characteristics
--

## - DC (At various voltages)
--

## - Single Phase AC (Commonly 110-240V 50/60 Hz)
--

## - Three Phase AC

## ...
---
# Different Requirements at the Output
--

## - DC (Regulated, constant magnitude)
--

## - Adjustable DC
--

## - AC (Constant frequency, variable magnitude)
--

## - AC (Variable frequency and magnitude)

---
# Control is almost always needed
--

## - Output Voltage Regulation
--

## - Overload Protection
--

## - Power Quality
--

## - Frequency Fixation (i.e. grid connected inverters)

## - Frequency Control (i.e. motor drives)

## ...
---
# Control is almost always needed
--

---
# Classification wrt Switching Characteristics
--

## - Line frequency (naturally commutated) converters
--

## (e.g. diode rectifiers)
--

## - Switching (forced-commutated) converters
--

## (e.g. switched mode power supplies)

##  -Resonant converters (zero voltage or zero current switching)

---
# Basic Building Blocks
--

## - AC/DC Converters (aka Rectifiers)
--

## - DC/AC Converters (aka Inverters)
--

## - DC/DC Converters (e.g. SMPS)
--

## - AC/AC Converter (e.g. Cycloconverter)
