An inverter that converts a direct current into an alternating current is called a DC-AC inverter. However, the term “inverter” generally refers to the equipment that combines an AC-DC converter (that changes an alternating current into a direct current) and a DC-AC inverter so as to be able to generate arbitrary frequencies and voltages. Figure
For example, in high-voltage direct current (HVDC) transmission, a DC current travels a long distance before being converted back into AC. This means a DC current is supplied via a large reactor. Since the DC side must be treated as a current source, a current source type inverter is used for HVDC applications.
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 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).
10.1109/IEEESTD.2020.9097534. It is a fact that the voltage quality at the grid connecon point varies not only from site to site, b ut also over me. Thus, in the case of poor grid voltage condions, for exa mple, an already exisng DC component can negavely affect the DC current component of the converter.
These DC fault currents MUST NOT be mixed up with DC current injection! The standard defines the requirements for an automatic AC disconnect interface – it eliminates the need for a lockable, externally accessible AC disconnect. When will PV be competitive?
