Introduction

Mohammadreza Lak received his B.Sc, M.Sc, and Ph.D. degrees in electrical engineering. His research interest lies broadly in the area of microgrids, power conversion systems, renewable distributed generation, and artificial intelligence.
he has worked on DC/AC three-level T-type inverters to reduce neutral point voltage ripple (improve dc-link capacitors' lifetime), control neutral point voltage offset (balancing control for improving power quality and also asymmetric control for enhancing energy harvesting in PV systems), and suppress leakage current (reduce EMI, motor bearings damage, motor winding insulation breakdown, and potential effect in PV systems). Besides, he has worked on modulation and commutation methods for AC/AC matrix converters to reduce switching losses, output voltage error, and output current distortion. 
Moreover, Mohammadreza Lak has been involved in the planning, redesigning, and scheduling of microgrids, taking into account the high penetration of renewable sources, grid-forming inverters, electric vehicles as mobile energy storage, and load uncertainty. In this regard, he has developed expertise in exact and heuristic optimization methods for energy management, neural network computing methods for forecasting PV system generation, and demand response programs.

Welcome to our laboratory focused on high-power electronic inverters and their applications in DC/AC power conversion. With the increasing global demand for energy, there is a growing emphasis on the development of high-power inverters. In line with this goal, our laboratory is currently undertaking a project to investigate the carrier-based implementation of synchronous, interleaved, and integrated modulations for dual-parallel three-level T-type inverters (3LTIs). These investigations will not only contribute to the field of high-power electronic inverters but also have significant implications for industries that rely on high-power and high-reliability DC/AC power conversion. Industries such as renewable energy, and grid integration are among those that stand to benefit from the outcomes of this research project. The developments made in our laboratory will contribute to improving the efficiency, reliability, and performance of power conversion systems in these sectors, paving the way for enhanced utilization of renewable energy sources. We are committed to pushing the boundaries of knowledge in the field of high-power electronic inverters and making significant contributions to the advancement of sustainable energy systems.
Join us in this exciting journey as we explore new frontiers in high-power electronic inverters and shape the future of DC/AC power conversion for a more sustainable and energy-efficient world.


Research Topics

our laboratory is currently undertaking a project to investigate the carrier-based implementation of synchronous, interleaved, and integrated modulations for dual-parallel three-level T-type inverters (3LTIs).
The dual-parallel 3LTIs consist of two individual 3LTIs connected to a shared DC-link, with a common neutral point between them. The control of these dual-parallel 3LTIs can be achieved through various modulation methods, including synchronous, interleaved, and integrated approaches. In this project, our objective is to specifically focus on the integrated modulation approach for dual-parallel 3LTIs.
