An inverter drive converts fixed-frequency, fixed voltage AC power from the mains supply into variable frequency, voltage and current output waveform, this allows for accurate control of three phase electric motors.
Internally, a rectifier turns AC power into DC, which is smoothed by capacitors, and then an inverter (using IGBTs) converts it back to adjustable AC.
An inverter commonly uses methods like Pulse Width Modulation (PWM) to convert power.
An inverter optimizes a motor's power usage to meet demand, often resulting in significant energy savings, especially in fan and pump type applications.
Allows accurate speed regulation, torque control, and soft-start capabilities, protecting motors from mechancal stress.
By eliminating harsh starts and running at lower speeds, this can decrease wear and tear on epensive machinery.
Used in HVAC (heating ventillation and air conditioning) systems, conveyors, water pumps, fans, mixers, compressors and various other types of industrial machinery
