Analytical & mathematical computation

With Maple, from Waterloo Maple Inc., the user only needs is to enter the equations and solve them. The process is neater and easier. The power system of NCR consists of single-phase power modules connected between the lines and neutral of the three-phase source. The total number of modules in a system depends on the load of the system. Because the number is not necessarily a multiple of three, the line currents are, in general, unbalanced. The outputs of all the modules are paralleled. Power sharing control lines ensures that all modules draw the same power. With four power modules installed, adding resistance to the neutral line caused the modules to latch-up. Though this behavior was not a problem because the amount of resistance required to induce latch-up far exceeded the value that would occur in practice, it required an explanation and an assurance that it would not occur under more realistic conditions.
