D-Q current controller design the frame for a single-phase inverter is a challenging task, as there is only one real current signal in the circuit, so it is necessary to create an orthogonal signal block to create a virtual orthogonal signal. Nevertheless, AC variable can be changed to equivalent DC variable via α-β/d-q transformations.
For controlling single-phase inverters connected to the grid, using inverter voltage regulation principles using PWM signal modulation techniques, the research team focused on inverter controls the distribution of active and reactive power. to the grid, resulting in almost unity of the power factor in the system.
Nevertheless, using a D-Q controller that does not need to create a perpendicular phase signal makes it easier to operate [3-9]. The current control scheme for the inverter with a D-Q frame connecting to a single-phase grid, signal blocks are required orthogonal (OSQ) to create a perpendicular virtual signal.
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.
