This report covers effort to develop a microprocessor-based controller for the Delco 15 KW power conditioner. Continuing from the microprocessor selection, the previous task, the controller hardware was developed and tested during this task. The controller software will be developed in the next task. The controller hardware conforms closely to the controller baseline design concepts of Task 2. A variation from the baseline did occur in the converter SCR commutation sense circuitry. The existing Delco commutation sense signals will not be used by the controller breadboard. Instead, a more direct and perhaps more reliable method of sensing the converter SCR commutation will be implemented with optical couplers. This method is presented in detail in the report.
