The main task of power electronics is to control and convert electrical power from one form to another. The four main forms of conversion are:
AC to DC conversion
DC to AC conversion
DC to DC conversion
AC to AC conversion
"Electronic power converter" is the term that is used to refer to a power electronic circuit that converts voltage and current from one form to another. These converters can be classified as:
Rectifier converting an ac voltage to a dc voltage
Inverter converting a dc voltage to an ac voltage
Chopper or a switch-mode power supply that converts a dc voltage to another dc voltage
Cycloconverter and cycloinverter that converts an ac voltage to another ac voltage
In addition, SCRs and other power semiconductor devices are used as static switches.
Now that you have learnt about DC to DC converter and inverters, let us look at the summary of concept that we must know.
