Problem statement: Powering traffic lights, which need to be in operation on a continuous basis for reasons of safety, consumes a considerable amount of energy. Hence, determining a cost-effective means of providing this energy to operate them is an important engineering problem. Assume that a typical intersection has a set of 48Vdc LED traffic lights that consume an approximately constant 300W of power. Next, suppose it is desired to have a 24Vdc (nominal) 260W-peak solar panel provide power to the traffic lights, with the utility grid (120Vrms) supplying the power difference between the solar panel output and the load demand. Assignment: Design a power conversion circuit that interfaces the solar panel and the grid to the 48Vdc 300W load, which satisfies the following requirements: The 48Vdc load must be supplied with 300W of power even as the solar panel voltage ranges between 0 and 37V dc, and its power ranges from 0 to 260W, due to changing light conditions. The load voltage must be within the range of 48Vdc = 1% during steady-state conditions, and 48Vdc +3% during extreme transient (change in light intensity at maximum rate of 5000 W/m2 per second) conditions Problem statement: Powering traffic lights, which need to be in operation on a continuous basis for reasons of safety, consumes a considerable amount of energy.
