s to verify the technical feasibility of the proposed system. The CPU supplies a maximum voltage of 24 V DC, at a current of 10 A, supplied by a wind/PV/battery hybrid energy system. The prototype is of a smaller size compared to the actual proposed system. However, the architecture is maintained. The CPU is controlled by a microcontroller, which regulates the voltage output of the hybrid system, using the PWM technique. Furthermore, the system uses a fixed potential concept, to manage the controller. Moreover, remote monitoring is being experimented with, where the unit monitors the voltage, current and upload the readings on the Cloud storage, for remote accessibility. The experimental results, therefore, confirm that the combination of solar and wind resources with battery storage can be employed for the operation of CPUs. ⃝c 2021 The Author(s).
