Abstract

An electronic load module system for testing voltage sources, such as power supplies, batteries, and fuel cells, is characterized by its ability to combine multiple load modules into a single virtual load for use with a first voltage source while simultaneously allowing other load modules in the same system to independently provide a load to an additional voltage source. The load modules may be combined in various configurations without altering the internal physical structure of the system. The system includes a first load module connected with the terminals of the voltage source and an associated control module connected with the first load module to supply a drive signal to the load module. The load system also includes a second load module. The second load module may be connected with the terminals of the voltage source in parallel with the first load module, or the second load module may be connected with the terminals of a second voltage source. A second control module is connected with the second load module to supply a drive signal to the second load module. The multiple load modules and control modules may be mounted in a single chassis.
