Návrh úpravy budicích obvodů a náhrady budicího měniče trakčních DC motorů lokomotivy

Abstract

The work describes the basic distribution of excitation circuits used in electric traction, and there are examples of control systems used, including their regulatory options. It is also described rough algorithm design converters, including draft power filter design values of switching elements and last but not least, the design of a cooling of semiconductor switches, including detailed calculations based on the derived formulas. The paper also presents a comparison of original and proposed solutions in the context of the needs of the equipment of locomotives.
