Special Issue Information

Dear Colleagues,

We are seeking submissions for a Special Issue of Machines entitled "Advances in Power Electronics for Electromechanical Energy Conversion and Drive Systems".

Today, power electronics circuits play a critical role in numerous applications, such as power supply, renewable energy systems, electrical vehicles, industrial systems, consumer appliances, electrical drive systems, etc. Therefore, new research focusing on power electronics circuits is highly desirable. Furthermore, identifying new and improved control strategies for power electronics circuits to enhance dynamic/steady-state performances is extremely important.

The aim of the present Special Issue is to compile original and high-quality papers and review articles which propose new/enhanced power electronics circuits for energy conversion and drive systems. Topics of interest include, but are not limited to, the following:

  • AC–DC, DC–DC, and DC–AC power converters;
  • Two/multi-level power electronics converters;
  • Renewable energy systems including wind, photovoltaic, etc.;
  • Electric drive systems;
  • New topologies and applications for power electronic converters;
  • Electrical machines and power electronics in electrical vehicles;
  • Observers and compensation in model mismatches.

This Special Issue will present cutting-edge research results in these emerging fields as a basis for the reliable and efficient operation of power electronics in electromechanical energy conversion and drive systems.

This study investigates the thermal performance of induction motors powered by multilevel H-bridge inverters using a novel pulse-width phase shift triangle modulation (PSTM-PWM) technique. Conventional PWM methods introduce significant harmonic distortion, increasing copper and iron losses and causing overheating and reduced motor lifespan. Through experimental testing and comparison with standard PWM techniques (LS-PWM and PS-PWM), the proposed PSTM-PWM reduces harmonic distortion by up to 64% compared to the worst one and internal motor losses by up to 5.5%. A first-order thermal model is used to predict motor temperature, validated with direct thermocouple measurements and infrared thermography. The results also indicate that the PSTM-PWM technique improves thermal performance, particularly at a triangular waveform peak value of 3.5 V, reducing temperature by around 6% and offering a practical and simple solution for industrial motor drive applications. The modulation order was set to M = 7 to reduce both the losses in the power inverter and to prevent the generation of very high voltage pulses (high dV/dt), which can deteriorate the insulation of the induction motor windings over time.
