What is a current source inverter?
Compared with the voltage source inverter, the current source inverter has the boosting characteristics, and the AC side does not need a complex and bulky filter unit, but it also has the problem of current control of the DC energy storage inductor.
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.
Does hysteresis control a grid-side current source grid-connected inverter with a DC chopper?
This paper studies the control strategy of a single-phase five-switch current source grid-connected inverter with a DC chopper. Firstly, hysteresis control is performed on the chopper to realize the constant output of the DC energy storage inductor current, which reduces the design difficulty of the grid-side current control system.
What are grid-connected inverters (GCIS)?
The grid-connected inverters (GCIs) controlled by traditional Current-Source Mode (CSM) and Voltage-Source Mode (VSM) face challenges in simultaneously meeting the requirements for small-signal stability, power-response, and grid-support.
