Abstract

Proportional-integration (PI) controller scheme is implemented to control the phase voltage of the customer-end single-phase inverter in a low-voltage DC (LVDC) distribution system. In the inverter output, the LC-filter is used. In order to avoid resonances caused by the filter, the feedback and the feedforward filteration is used. It is shown that basic PI control system cannot drive the steady-state capacitor (load) voltage amplitude error to zero. To compensate the error, an outer-loop RMS voltage control is applied. The study shows that the system behaviour using a PI control is quite good.
