The output voltage of an inverter can be adjusted by employing the control technique within the inverter itself. This control technique can be accomplished by the following two control methods. Pulse Width Modulation Control.
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.
In the case of variable speed drives, inverters with voltage control help in achieving voltage variation. Voltage control of inverters is employed in order to compensate for changes in input dc voltage.
