| Abstract: | A digital controlled DC source was designed adopting AT89C52 version single chip microcomputer. The work principle of hardware circuit and the calculational method of parameters were introduced detailedly , and gave the tested result. Expressing the design is simple, stable in output of the electric current, small step, higher accuracy, simple and maneuverable, low-cost and easy to generalize. |
