Special Issue Information

Dear Colleagues,

Energy harvesting devices that utilize microelectromechanical systems (MEMS) technology can generate electrical energy from a variety of ambient energy sources, such as solar, mechanical, thermal, or electromagnetic. These devices typically generate electrical energy by converting energy from various environments using miniature sensors or energy harvesters. Energy harvesting devices composed of mechanical vibration, photovoltaic transduction, vibration transduction, piezoelectric transduction, electromagnetic transducers, electrostatic transducers, etc., combined with MEMS technology have the potential to power a wide range of power-consuming applications, including devices such as wireless sensors, Internet of Things (IoT) devices, and wearable electronics, making them a very novel and interesting topic for research and development.

Power electronics combines solid-state electronics and the latest semiconductor technologies for energy and power harvesting, conversion, and control applications. Therefore, this Special Issue aims to invite original research papers, short communications, and review articles focusing on the latest developments and technologies in the integration of power electronics with sensors and transducers in various environments for the application of MEMS sensors in enhanced energy harvesting systems.

A new and improved sliding mode control (NISMC) with a grey linear regression model (GLRM) facilitates the development of high-quality pure sine wave inverters in photovoltaic (PV) energy conversion systems. SMCs are resistant to variations in internal parameters and external load disturbances, resulting in their popularity in PV power generation. However, SMCs experience a slow convergence time for system states, and they may cause chattering. These limitations can result in subpar transient and steady-state performance of the PV system. Furthermore, partial shading frequently yields a multi-peaked power-voltage curve for solar panels that diminishes power generation. A traditional maximum power point tracking (MPPT) algorithm in such a case misclassifies and fail to locate the global extremes. This paper suggests a GLRM-based NISMC for performing MPPT and generating a high-quality sine wave to overcome the above issues. The NISMC ensures a faster finite system state convergence along with reduced chattering and steady-state errors. The GLRM represents an enhancement of the standard grey model, enabling greater accuracy in predicting global state points. Simulations and experiments validate that the proposed strategy gives better tracking performance of the inverter output voltage during both steady state and transient tests. Under abrupt load changing, the proposed inverter voltage sag is constrained to 10% to 90% of the nominal value and the voltage swell is limited within 10% of the nominal value, complying with the IEEE (Institute of Electrical and Electronics Engineers) 1159-2019 standard. Under rectified loading, the proposed inverter satisfies the IEEE 519-2014 standard to limit the voltage total harmonic distortion (THD) to below 8%. Full article
