FIGURE 3.25 Simulation results of a double-stage single-phase grid-connected PV system, where solar irra-
diance step changes have been considered and an ambient temperature of 25 °C is taken into account: (a), PV
output power P pv (1 kW/div); (b), grid voltage v g (200 V/div) and grid current (20 A/div); (c), DC-link voltage
v DC (25 V/div) and time (40 ms/div).
