About the Training

With the growing importance for reducing the dependence on the non-renewable sources of energy, photovoltaic energy conversion has gained much popularity as a viable green alternative. Although PV modules are cheaper than ever before, there is a desperate need to maximize the extracted energy to gain practical returns on the huge investment on PV arrays. One of the main factors detrimental to the PV energy yield is partial shading. To minimize the mismatch losses among the modules, it is desired to reconnect the conventional series- parallel array so as to distribute the shading effect over the entire array without altering the electrical connections of the modules. Whatever be the physical configuration of the array, the output power-voltage characteristics are non-linear, with the PV power dependent on the voltage at which it is extracted. Thus there is a need for Maximum Power Point Tracking technique, which requires power electronic interfaces such as DC/DC or DC/AC converters.

This course is designed to address the effect of partial shading on PV arrays, and methods to extract maximum power under all environmental conditions. The workshop methodology includes classroom lectures, case study simulations, practical demonstrations and hands-on experience on MPPT implementation and PCB design of power converters.

The five-day Training shall have sessions on:

• Modelling of PV cells
• Simulation of electrical characteristics of PV array
• Control of grid connected PV inverters
• Impact of partial shading on PV systems
• Design and implementation of Power Converters
• Laboratory-based training module on “Design of Printed Circuit Boards for Power Converters”
• Laboratory-based training module on “MPPT Implementation using microcontroller”.

The five-day course will be spread over two weekends. The course will enlighten the participants with new paradigms and findings, practical challenges encountered and the possible solutions for the challenges faced in solar photovoltaic systems. The workshop is anticipated to enhance the technical interaction between groups paving the way for an overall fortification of technical capabilities of the power electronics community.
