Abstract: The present disclosure provides alfalfa plants exhibiting broad spectrum resistance to Race 1, Race 2, and Race 5 anthracnose. Such plants may comprise novel introgressed genomic regions associated with disease resistance from Race 1, Race 2, and Race 5 anthracnose. In certain aspects, compositions, including novel polymorphic markers and methods for producing, breeding, identifying, and selecting plants or germplasm with a disease resistance phenotype are provided. Also provided are alfalfa varieties designated as C0416C4164 and H0415C4114. Provided by the invention are the seeds, plants and derivatives of alfalfa varieties C0416C4164 and H0415C4114. Also provided by the invention are tissue cultures of alfalfa varieties C0416C4164 and H0415C4114, and the plants regenerated therefrom. Still further provided by the invention are methods for producing alfalfa plants by crossing alfalfa variety C0416C4164 or H0415C4114 with itself or another alfalfa variety and plants produced by such methods.

Abstract: A circuit for use with a stator winding of a rotating or linear electrical machine, the stator winding having a number of coils linked by the same number of points of common coupling, includes an electronic commutator circuit having the same number of switching stages, each connected between a respective one of the points of common coupling and first and second main dc lines. Each switching stage includes first and second reverse blocking semiconductor power devices. A voltage clamping circuit includes the same number of clamping stages, each connected between a respective one of the points of common coupling and first and second auxiliary dc lines. Each clamping stage includes first and second diodes and first and second capacitors common to the various clamping stages. A dc to dc converter selectively discharges the first and second capacitors to the first and second main dc lines.
