A grid-connected PV array consisting of sixteen150-W modules can be arranged in a number of serie...
Assume you have the circuit below injecting power from a PV array to the grid. The single-phase H-bridge inverter is designed so that it is capable of injecting up to 2.5 kW into the grid when the grid voltage is 120 Vrms and the total resistance between the inverter and the grid is 0.5 Ohm (i.e., the inverter modulation index equals 1 in these conditions). Under these conditions, calculate: - The inverter output voltage Viny - The dc link voltage...
