    ECO REFERENCE MANUAL VARIABLE FREQUENCY INVERTER. An electronic converter which converts Direct Current (DC) to Alternating Current (AC) is known as an inverter. Electronic speed controllers for AC motors usually convert the AC supply to DC using a rectifier, and then convert it back to a variable frequency, variable voltage AC supply using an inverter bridge.
