This paper presents the design of a discrete-time control scheme for the current injected into the grid by a single-phase voltage source inverter (VSI). The VSI is connected to the grid by means of an LCL filter that attenuates the switching harmonics present in the output waveform of the inverter.
A common control method for off-grid inverters is multiple-loop control with a PI compensator. The output of the voltage loop is the reference value for the current loop. In this model, the common control method is utilized except that the voltage reference and sampling signal is the RMS value of output voltage.
The proposed control was tested with a laboratory prototype that was mounted following the scheme shown in Fig. 1. The single-phase inverter is formed by using two branches of the SKS 22FB6U+E1CIF+B6CI 13 V12 three-phase inverter supplied by SEMIKRON. The DC-side of the inverter is connected to a programmable Regatron TC.GSS DC source.
In this model, the common control method is utilized except that the voltage reference and sampling signal is the RMS value of output voltage. Besides, an additional notch filter is used to attenuate an amplitude of 100Hz ripple of output voltage. Conventional voltage loop directly uses sampling AC voltage to produce the error signal.
However, a short array length brings a 50Hz frequency ripple into the RMS value, which causes oscillation in the control. After many tests, a window width of 4 was found to be a good value in this model. This application note introduces the implementation of single phase off-grid inverter with digital control in PLECS.
