Design and Realization of Programmable Electronic Load for Aerospace Vehicle Testing

Aerospace vehicle is connected to the ground system through umbilical connectors. Before connecting the umbilical connectors to the flight worthy system, it is essential to test and cleared the ground system. Umbilical Test Jig (UTJ) with passive resistors is not able to simulate the actual power of aerospace vehicle subsystems. The Automated Umbilical Test Jig (AUTJ) incorporates a programmable electronic load which can simulate the actual power requirement of aerospace vehicle sub-systems and measure the values. The present paper deals with design and realization of Programmable Electronic Load (PEL) based on active load and microcontroller (MSP430F6659).
