Abstract The Photovoltaic systems have a slow dynamics of convergence toward the maximum power point (MPP), especially those equipped by the Boost converter based on the Conventional Incremental Conductance technique. This paper presents the simulation and hardware implementation of auto-scaling variable step-size MPPT in low cost and low power consumption μ-controller (PIC16F877A). Design and simulation of the proposed system are presented using ISIS PROTEUS. The two MPPT techniques, conventional IncCond method and variable step-size method are simulated in the ISIS PROTUES environment. The simulation results show the high tracking accuracy and fast speed convergence of the proposed method. Indeed, the experimental results are closely similar to those of simulation and also prove the advantages of the proposed technique, such as its reliability and accuracy in tracking the MPP. The suggested MPPT system reduces the complexity in implementation and cost of the photovoltaic systems.

A quad, small form-factor pluggable 28 Gbps optical transceiver design scheme is proposed. It is capable of transmitting 50 Gbps of data up to a distance of 40 km using modulation signals with a level-four pulse-amplitude. The proposed scheme is designed using a combination of electro-absorption-modulated lasers, transmitter optical sub-assembly, low-cost positive-intrinsic-native photodiodes, and receiver optical sub-assembly to achieve standard performance and low cost. Moreover, the hardware and firmware design schemes to implement the optical transceiver are presented. The results confirm the effectiveness of the proposed scheme and the performance of the manufactured optical transceiver, thereby confirming its applicability to real industrial sites.
