Abstract
The DC load system with the main component PIC16C716 low-power MCU,can work in the constant current,constant voltage,constant resistance and constant power four modes.Related hardware circuits are provided.With optimal design of solftware,the system has high load precision,good load stability and convenientness of the regulating control.By practical test to the system,the results show that the measurement parameters error is less than 0.5% and its ability is stronger than similar products.
