This person is not on ResearchGate, or hasn't claimed this research yet. Direct quadrature (DQ) synchronous reference frame transformation-based current controllers are utilized due to their superior performance, while they drive on dc quantities, attaining zero steady-state error, and are highly compatible for single-phase grid-tied inverters.
For three-phase voltage-source inverters, the active and reactive currents can be controlled separately in the dq -frame, in which the current signals are the dc components and proportional to active/reactive powers . However, since only one current signal exists in the circuit, there are barriers to implement such controllers for SPVSIs.
