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 PV Grid connected inverter works?
Before the pv grid connected inverter is connected to the grid for power generation, it needs to take power from the grid, detect the parameters such as voltage, frequency, phase sequence, etc. of the grid power transmission, and then adjust the parameters of its own power generation to be synchronized with the grid electrical parameters.
What happens if the inverter outputs reactive power at night?
When the inverter outputs reactive power at night, if the 'Abnormal PID Compensation Detection' parameter is enabled, the inverter will shut down automatically if it detects an abnormal status. Otherwise, the inverter output current harmonics will be optimized.
How do I set the working mode of the inverter?
To set the working mode of the inverter, choose Function Menu > Settings > Protect Parameters. The inverter's working mode is determined by the grounding status at the DC side and the connection to the power grid. Before setting the parameters, the inverter performs a self-check to detect the insulation resistance of the input side with respect to ground to ensure device safety.
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.
