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 a general-purpose inverter work?
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. V/f control is a method of controlling a motor by supplying a specific current to the coil to output a specific torque.
What are amorphous magnetic cores?
Amorphous magnetic cores have superior magnetic characteristics, such as lower core loss, when compared with conventional crystalline magnetic materials. These cores can offer superior design alternative when uses as the core material in the following components:
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.
What are the parameters of an inverter?
The main basic parameter of the inverter is the Nominal AC power Pnom, that is the maximum power the inverter is able to deliver to the grid in any conditions. Some manufacturers specify also a Maximum AC power Pmax, as a power which may be attained in specific conditions.
What happens if the inverter is over vmppmax?
Therefore there will be no extra heat, no extra wear of the inverter, it is a safe behavior. The necessary voltage for limiting the power to PNomDC may be over the VmppMax value. In these cases there is no possible operating range, and the inverter has to stop, leading to very high overload loss.
