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...

2. (15 pts) The reason why high voltage in power grid is used to transmit electric power is that it can reduce power waste along the transmission lines known as transmission loss. Suppose that a power station delivers 1,000 kW of power at 10,000 V to a city through wires with total resistance 3.0 22. How much power can be saved if the same power is delivered at 50,000 V?
