Question:

A hybrid solar cell and diesel power distribution system has been proposed and tested (Lee, 2007). The system has been shown to have a very good uninterruptible power supply as well as line voltage regulation capabilities. Figure P5.40 shows a signal flow diagram of the system. The output, V_Load, is the voltage across the load. The two inputs are I_Cf, the reference current, and I_Dist, the disturbance representing current changes in the supply.

a. Refer to Figure P5.40 and find the transfer function V_Load(s)/I_Cf(s).

b. Find the transfer function V_Load(s)/I_Dist(s).
