How does an inverter work?
The inverter first converts the input AC power to DC power and again creates AC power from the converted DC power using PWM control. The inverter outputs a pulsed voltage, and the pulses are smoothed by the motor coil so that a sine wave current flows to the motor to control the speed and torque of the motor.
How does an inverter control a motor?
An inverter uses this feature to freely control the speed and torque of a motor. This type of control, in which the frequency and voltage are freely set, is called pulse width modulation, or PWM. The inverter first converts the input AC power to DC power and again creates AC power from the converted DC power using PWM control.
How does a general-purpose inverter work?
The voltage output from the inverter is in pulse form. The pulses are smoothed by the motor coil, and a sine wave current flows. As a result, the output from a general-purpose inverter cannot be used for equipment other than motors.
Why are multilevel inverters important?
Multilevel inverters have become an essential component in modern power conversion systems, especially for industrial applications and renewable energy integration. These systems offer significant advantages, including lower harmonic distortion, reduced electromagnetic interference, and improved power quality 1.
Why do inverters use a reactor?
A reactor is used to suppress harmonics generated from an inverter. There are DC reactors and AC reactors. Both of them work to suppress rapid changes in the current. The current distortion from the normal current sine wave generated when AC is converted to DC and then smoothed.
How to select an inverter?
Basically, select an inverter which fits the maximum applicable motor capacity of the selected motor. After selecting an inverter, check if it meets the both of the following conditions. If not, select an inverter with one size larger in capacity and check again. Note: 1.
