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 directly adjust the voltage applied to a load by varying the conduction ratio (i.e., the pulse width of a PWM signal).
Current source type inverters control the output current. A large-value inductor is placed on the input DC line of the inverter in series. And the inverter acts as a current source. The inverter output needs to have characteristics of a voltage source.
Voltage and current controlled inverters look quite different on a sub 20ms time scale. On a longer time scale (ie seconds) however, inverters used for injection of energy from a PV array directly into the grid are controlled as power sources ie. they inject “constant” power into the grid at close to unity power factor.
What Is The Difference between Current Source Inverter and Voltage Source Inverter? . In the field of power electronics, Current Source Inverters (CSIs) and Voltage Source Inverters (VSIs) are two fundamental types of inverters used to convert direct current (DC) into alternating current (AC).
Table 2.1 provides an overview of inverter categories. Voltage-type PWM inverters are most commonly used. These inverters are further divided into two categories, depending on the commutation method used: 120° commutation primarily used for small motor applications and 180° commutation used for many motor and power supply applications.
The two primary types of inverters—Voltage Source Inverters (VSIs) and Current Source Inverters (CSIs)—differ in their approach to this conversion process. Selecting the right inverter type depends on factors such as the nature of the power source, desired control precision, application requirements, and system complexity. What is Inverter?
