Design and implementation of the real-time regulation electronic load module based on DSP

This paper introduce a design scheme of a electronic load module which have real-time performance and can regulate current dynamically. We design the CAN network use the internal embedded CAN controller of DSP, at the same time we study characteristic of MOSFET at the condition of the drive voltage changes dynamically, and design its drive circuit use the DAC chip. Equipped with this electrical load module which adopts this design scheme, the power test system achieves the real-time regulation of the load current, and realizes the function of testing the object´s dynamic operation performance.
