Abstract

A power generator and method of use for providing symmetrical power. In the present invention, the output winding of a generator is center-tapped at the point of mean voltage differential between each of its two output terminals. The center-tap is grounded such that one-half of the output potential appears across each half of the output winding. Full, symmetrical voltage is applied to the load when the output terminals are connected to the load and the load is grounded.

Claims

1. An improved ac generator, said generator comprising:

an output winding having a pair of output terminals;

a center tap terminal located at the point of mean voltage differential between the two output terminals of said output winding, wherein said center tap terminal is grounded;

each of said output terminals of said output winding being connected to an input terminal of said impedance load, wherein said impedance load is grounded.

2. An improved ac generator as in claim 1, wherein said generator is a three phase generator having three output windings, and each of said output windings of said generator is configured such that a center tap terminal is located at the point of mean voltage differential between each of its two output terminals;

each center tap terminal is grounded; and

grounding said ground terminal of said impedance load.

4. A method as in claim 3, wherein said generator is a three phase generator having three output windings, said method comprising configuring each of said output windings of said generator such that a center tap terminal is located at the point of mean voltage differential between each of its two output terminals;
