Difference between Converter and Inverter | Electrical Engineering Facts

In general way of common people’s understanding: These both words are used interchangeably by persons belonging to a different field than power electronics. They essentially mean to convey the functionality of the device (DC to variable freq AC) and as long as this is done, power electronics people (like me) do not bother to correct their usage of these two words.

Converters and inverters are electrical devices that convert current. Converters convert the voltage of an electric device, usually alternating current (AC) to direct current (DC). On the other hand, inverters convert direct current (DC) to alternating current (AC).

Converter vs Inverter 

Edit this comparison chart Converter Inverter
What it is Electrical devices that convert the voltage from alternating current (AC) to direct current (DC). Electrical devices that convert the voltage from direct current (DC) to alternating current (AC).
Types of Analog-to-digital converter (ADC) Digital-to-analog converter (DAC) Digital-to-digital converter (DDC) Square wave inverter Quasi-wave or Modified square wave inverter True/Pure Sine wave inverters
Applications Convert AC to DC; detect amplitude modulated radio signals; supply polarized voltage for welding. Convert DC electricity from solar panels, batteries or fuel cells to AC; micro-inverters for converting DC power from solar panels to AC for the electric grid; UPS uses an inverter to supply AC power when main power is unavailable; induction heating.
Disadvantages Poor current overload capacity; better quality Automatic regulators are more expensive than Mechanical regulators. Not ideal for inductive AC and motor loads; sensitive electronic devices can be damaged by poor waveforms by low batteries.
