Abstract: In order to meet the requirements of load programmable, automatic loading in DC power characteristic test, this paper raised a realization plan of programmable DC load test system based on single chip controller. The system took the single chip C8051F020 as the main control unit, combined with existing resistance loading technology to realize constant current, constant resistance and constant power control for programmable DC load with better test accuracy in each mode, being able to carry out more simple, fast, reliable output characteristics test for power source, transformer etc electronic equipment.
Key words: C8051F020 single chip; programmable DC load; constant current; constant resistance; constant power
