Three-phase inverter voltage relationship
The three pole voltages of the 3-phase square wave inverter are shifted in time by one third of the output time period. . However, most 3-phase loads are connected in wye or delta, placing constraints on the instantaneous voltages that can be applied to each branch of the load. For the wye connection, all the “negative” terminals of the inverter outputs are tied together, and for the detla connection, the inverter. . In order to realize the three-phase output from a circuit employing dc as the input voltage a three-phase inverter has to be used. In this chapter the concept of switching function and the associated switching matrix is explained. It is widely used in various applications such as motor drives, renewable energy systems, and power transmission. [PDF Version]

How do inverters provide grid services?
In order to provide grid services, inverters need to have sources of power that they can control. This could be either generation, such as a solar panel that is currently producing electricity, or storage, like a battery system that can be used to provide power that was previously stored.
Why do we need grid-connected inverters?
The new power system has motivated the evolution of grid-connected inverters (GCIs) to provide grid-support services [3, 4], which has put forward further requirements for the small-signal stability, power-response performance, and grid-support capability of GCIs.
What is a grid-tie inverter?
A grid-tie inverter converts direct current (DC) into an alternating current (AC) suitable for injecting into an electrical power grid, at the same voltage and frequency of that power grid. Grid-tie inverters are used between local electrical power generators: solar panel, wind turbine, hydro-electric, and the grid.
Why do we need a grid-following inverter?
Increasing use of inverters has to lead to the development of more sophisticated control approaches alongside posing a variety of stability and power quality challenges [1, 2]. When the grid is healthy, multiple inverters operating in grid-following mode are tied to the grid to inject economic power.
