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 voltage control is primarily achieved by varying the firing. .
The external control of dc input voltage is a technique that is adapted to control the dc voltage at the input side of the inverter itself to get a desired. .
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. Voltage control within the Inverter: The dc link voltage is constant and the inverter is controlled to provide-both variable voltage and variable frequency. As the link voltage is Constant a simple diode rectifier may be employed on the line side. [pdf]
