Voltage and Harmonic Control of Inverters: Voltage and Harmonic Control of Inverters – In applying Inverters for motor control both V and f (keeping V/f constant) need to be varied.
An Inverter Drive (VFD) works by taking AC mains (single or three phase) and first rectifying it into DC, the DC is usually smoothed with Capacitors and often a DC choke before it is connected
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.
Basically, there are three techniques by which the voltage can be controlled in an inverter. They are, Internal control of Inverter. In this method of control, an ac voltage controller is connected at the output of the inverter to obtain the required (controlled) output ac voltage.
Voltage control of inverters is employed in order to compensate for changes in input dc voltage. Basically, there are three techniques by which the voltage can be controlled in an inverter. They are, Internal control of Inverter.
In this, the inverter circuit is fed from a constant dc voltage source and a controlled ac voltage is obtained at the output terminals by turning ON and OFF the switching components in the inverter circuit. The main drawback of this method is that it requires very low turn-ON and turn-OFF time thyristors which are very expensive.
Internal control of Inverter. In this method of control, an ac voltage controller is connected at the output of the inverter to obtain the required (controlled) output ac voltage. The block diagram representation of this method is shown in the below figure.
The control circuit regulates the operation of the inverter. It manages the frequency and voltage of the output AC power. This circuit includes various sensors and microcontrollers to ensure the motor operates at its optimal performance according to preset conditions.
