MPPT Control and Architecture for PV Solar Panel with Sub-Module Integrated Converters

Abstract

Photovoltaic (PV) solar systems with series-connected module integrated converters (MICs) are receiving increased attention because of their ability to create high output voltage while performing local maximum power point tracking (MPPT) control for individual solar panels, which is a solution for partial shading effects in PV systems at panel level. To eliminate the partial shading effects in PV system more effectively, sub-MICs are utilized at the cell level or grouped cell level within a PV solar panel. This study presents the results of a series-output-connection MPPT (SOC-MPPT) controller for sub-MIC architecture using a single sensor at the output and a single digital MPPT controller (sub-MIC SOC-MPPT controller and architecture). The sub-MIC SOC-MPPT controller and architecture are investigated based on boost type sub-MICs. Experimental results under steady-state and transient conditions are presented to verify the performance of the controller and the effectiveness of the architecture.

Azimuth Angle and Magnetic Declination to Maximize Solar Panel Efficiency (Solar Tracking System)

“…The benefit of this design is that it maximizes the solar panel efficiency which will reduce the number of solar panels for operation purposes [9]. The solar tracker has been designed in this project which helps in positioning the solar panel in the direction of sun so that highest number of photons strikes on the panel [10]. As a result, maximum solar energy is utilized for generation of electricity [11].…”

Design and implementation of a novel zero‐current switching method for low‐power DC–DC converters

“…Power management systems in many portable systems, such as wireless sensors, internet of things (IoT) devices, RF transceivers, wearable electronic devices, energy-harvesting applications, and medical devices, should be able to use battery energy efficiently and produce several supply voltages with variable currents to supply the required power of the system. Therefore, a dc-dc converter capable of multiple switching is needed [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. In systems with other energy sources such as photovoltaic cells (PV), thermoelectric generators (TEG), etc., in addition to the battery, they are also used to provide the system's output power.…”
