      <title>ASSURED ENERGY RECEPTIVITY STUDY</title>
      <link>https://trid.trb.org/View/30815</link>
      <description><![CDATA[The objective of this study is to compare a conventional chopper-controlled train propulsion system without regeneration with two schemes of regeneration: (1) natural receptivity and (2) assured receptivity. A system that employs natural receptivity regeneration converts the kinetic energy of braking trains to electrical energy which is used to power onboard equipment. An assured receptivity regeneration system operates in a manner similar to a natural receptivity system, except that the excess electrical energy is stored, dissipated, or redistributed. The objective of this study is to quantify savings achieved in power consumption and cooling capacity by the use of a regenerative braking system, and compare them to the added costs of the electrical system for both natural and assured energy receptivity.]]></description>

      <title>THYRISTOR CHOPPER CONTROLS FOR D.C. TRACTION SYSTEMS</title>
      <link>https://trid.trb.org/View/39985</link>
      <description><![CDATA[Choppers were first designed more than ten years ago. Owing to the advantages of this design, such as the low-loss and stepless control of the motor voltage and current without using mechanical contracts, as opposed to conventional rheostatic control, the chopper is finding increasing application in short-distance traction systems. The article describes design concepts for the running and braking schemes developed to date as well as the equipment required.]]></description>
