Voltage source type inverters control the output voltage. A large-value capacitor is placed on the input DC line of the inverter in parallel. And the inverter acts as a voltage source. The inverter output needs to have characteristics of a current source. In the case of low impedance load, series reactors are needed for each phase.
Inverters are classified into many different categories based on the applied input source, connection wise, output voltage wise etc. In this article, we will see some of the categories. The inverter can be defined as the device which converts DC input supply into AC output where input may be a voltage source or current source.
Selecting the right inverter type depends on factors such as the nature of the power source, desired control precision, application requirements, and system complexity. A Voltage Source Inverter (VSI) is an electronic device that converts a fixed DC voltage into a controlled AC voltage with adjustable frequency and amplitude.
The inverter is known as current source inverter when the input of the inverter is a constant DC current source. Stiff current is supplied to the CSI (current source inverter) from the DC source where the DC source have high impedance. Usually, a large inductor or closed loop-controlled current are used to provide stiff current.

Voltage-type inverters have higher output voltage and current than current-type inverters, and have a wider range of applications, suitable for more motor types and working environments. In summary,
Current-type VFDs manage motor speed via current, ideal for heavy tasks. Voltage-type VFDs adjust voltage and frequency, offering precise control and energy savings.

Voltage source type inverters are easier to control than current source type inverters. It is easier to obtain a regulated voltage than a regulated current, and voltage source type inverters can
For constructing inverters with high power ratings, 2 inverters (three-phase inverters) are connected in series for high voltage rating. For high current rating, 2 six-step three inverters can be
The inverters can be classified based on a number of factors like, the nature of output waveform (sine, square, quasi square, PWM etc), the power devices being used (thyristor transistor,
An inverter refers to a power electronic device that converts power in DC form to AC form at the required frequency and voltage output. Inverters are classified into two main categories − Voltage Source
