The hardware and software details of a microprocessor-controlled digital shunt regulator (DSR) for solar power systems are presented. The DSR is briefly described, solar cell array section simulators are outlined, the operation and design of the dissipative analog shunt regulator are given, and the description and design of shunt current comparators are presented. In addition, the need for a special timing function and its design is discussed. Attention is given to the description of the microprocessor-controller, hardware implementation, software programs, and interfacing. The operation of the complete DSR system is summarized. Experimental results of the model system are presented. Some possible extensions are suggested. In conclusion, for solar power systems a digital shunt regulator is superior to other types of shunt regulators, and the use of a microprocessor for the control of the digital shunt regulator results in improved system performance. System flexibility is the chief advantage of a microprocessor-based system.
