Each inverter consisted of a single-phase IGBT fullbridge
with a switching frequency of 20 kHz and an L–C
output filter, using the parameters shown in Tables I and II. The
impedance of the lines connected between the inverters and the
load was intentionally unbalanced to properly test the control
behavior, as shown in the equivalent circuit of Fig. 17.
The outstanding features of the parallel system were experimentally
evaluated when the two-unit system shares a linear
load. Fig. 18 depicts the steady-state and the transient response
of the output currents and the circulating current (i1 − i2) when
a sudden load change occurs from no load to full load. As can
be seen, the circulating current remains very small even for
no-load conditions. These results show an excellent dynamic
response of the proposed controller for load-step changes.
The dynamic performance of the system was tested by
connecting unit 2, while unit 1 was supplying the linear load
constantly. As shown in Fig. 19, the derivative terms of the
proposed P/Q-sharing loop allow us to improve the transient
