1. A square-wave inverter has an R-L load with R=15 2 and L=10 mH. The inverter output frequency is 400 Hz (fundamental frequency). (a) Determine the values of the required to establish a load current which has a fundamental frequency component of 10 A rms with a = 0. (b) For a controlled full-bridge inverter, the dc source is 125 V and the switching frequency is 60 Hz. Determine the value of a to produce an output with amplitude of 100 V at the fundamental frequency.

A small  rm specializes in making  ve types of spare automobile parts.Each part is  rst cast from iron in the casting shop and then sent to the  nishingshop where holes are drilled, surfaces are turned, and edges are ground. Therequired worker-hours (per 100 units) for each of the parts of the two shops areshown below: Part 1 2 3 4 5Casting 2 1 3 3 1Finishing 3 2 2 1 1The pro ts from the parts are 30, 20, 40, 25, and 10 (per 100 units), respec-tively. The capacities of the casting and  nishing shops over the next month are700 and 1000 worker-hours, respectively. Formulate the problem of determiningthe quantities of each spare part to be made during the month so as to maximizepro t.
