How to Design an Optimal Electronic Load for High-Current, Low-Voltage Power Supplies (Part 3) (.PDF Download)

The design challenges for a high-power electronic load extend beyond the electronics. The best electronic load circuit will not function well without a good connection to the device under test. The connection should be easy to make and break, have extremely low electrical resistance, and minimize the physical path length for the current. Keeping the high-current path short and small in area reduces parasitic inductance that’s detrimental to the load current slew-rate performance.
