| Abstract | This paper describes the design and testing of a two-channel 52-kW pulsed load. Its main feature is exceptionally low parasitic inductance, on the order of 200 nH. Such low inductance was needed in view of microsecond high-current pulses; it was realized by a compact design and careful layout. Small size is a prerequisite for minimizing the inductance; it was achieved by forced liquid cooling. Non-inductive bulk resistors were used at a power rating far exceeding their specifications detailed for operation in air and were found adequate for their mission. They were housed in standard stainless steel drums. The cooling liquid (water-propylene-glycol mixture) was circulated through a heat exchanger. Multiple aspects of the design are described, including resistor choice, calculating the load inductance, choice of busbars, details of kinematic scheme, heat transfer, HV, safety and other considerations for cooling agents, etc. Special attention was paid to avoiding turbulent flow that could result in the resistor cracking. Inductance measurements showed close correspondence with the calculations. High-power testing showed reliable operation with overheat about 40 K above ambient. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
