What is the purpose of an inverter drive?

The purpose of an inverter drive is to convert AC mains (single-phase or three-phase) into a smoothed DC (direct current) supply to operate a motor. Inverters also introduce the ability to control speeds, acceleration and deacceleration time, braking methods, and torque.

What is a DC-AC inverter?

An inverter that converts a direct current into an alternating current is called a DC-AC inverter. However, the term “inverter” generally refers to the equipment that combines an AC-DC converter (that changes an alternating current into a direct current) and a DC-AC inverter so as to be able to generate arbitrary frequencies and voltages. Figure

What makes a direct drive inverter different from a micro-inverter?

Flexible power conversion: inverter can target DC through AC, including harmonic reduction for power conditioning functions. Modular: Direct Drive architecture is modular and scale-able, making it ideally suited for renewable energy applications. Unlike micro-inverters, only the minimum electronics necessary is duplicated per source.
