Energy consumption is expected to increase, as are the transport, commercial, residential, and industrial sectors. As a result, there is a substantial increase in demand, which is a consequence of the rising global standard of living. By reducing the true cost of energy, people can live better. The driving factor is the cost of energy, which is badly skewed by out-of-period cleanup expenses.?
Efficiency of conversion, especially regarding power usage, is a significant factor. Wide-bandgap semiconductors will contribute significantly to energy efficiency. Silicon carbide and gallium nitride have witnessed increasing success in the semiconductor device market in recent years. GaN is now used in mobile device chargers and charging systems. On the other hand, SiC devices have primarily been used in the field of electric mobility. In 2017, electric-vehicle manufacturers like Tesla chose to use SiC-based motor controllers, which boosted the efficiency of their systems.?

Automotive In-Cabin Wireless Charging Solution with Highly Integrated Controller
By Subramanyam Sankaran
Wireless charging technologies range from inductive, magnetic resonant, and capacitive to RF radiation, laser, acoustic, and other emerging ones. The inductive coupling technology is the frontrunner1; hence, its associated?Qi standard?is the most prevalent in wireless charging.
Rapid Control Prototyping of Synchronous Reluctance Motor Drives by Matlab/Simulink
By Marco Tursini, Lino Di Leonardo, Federico Verna and Davide Angrilli
The prototyping step has gained a fundamental role in achieveing the increasingly strict demands of performance, safety, and flexibility in the control of electrical drives. In particular, due to the increasing innovation and complexity of the proposed solutions in many sectors, rapid testing, and experimental validation have become mandatory to reduce the time-to-market and ensure appropriate performance and efficiency.

Improving the performance of DC-DC converters by using SMD packages with top-side cooling
By ?Marco Papaserio, Domenico Nardo, Daniela Cavallaro, Cristiano Gianluca Stella and Stefano Orlando
This paper analyzes the efficiency of?silicon MOSFETs?in surface-mount (SMD) packages with top-side cooling compared to bottom-side cooling packages in terms of thermal performance, lowering both thermal resistance and operating temperatures. It will show how reducing the junction temperature helps to boost power efficiency due to a smoother variation of the main silicon MOSFET parameters due to temperature changes such as RDS(on)?and Vth level as well as reduces total conduction and switching losses.
SiC MOSFET Isolated Gate Driver with PCB-Based Transformer
By Stefano Lovati
This article will present a transformer-based isolated gate driver for 3.3kV?SiC MOSFETs. Two VHF modulated resonant flyback converters, operating at a frequency of 20 MHz, generate both the PWM signal and the gate-drive power.
The high-voltage insulation feature (15 kVRMS) is provided by a?PCB-based air-core?transformer. With a low coupling capacitance of 5pF, this transformer strengthens the noise immunity even at high dv/dt of the SiC MOSFET. To assess the validity of the proposed solution, experimental results on 3.3kV discrete SiC MOSFETs will be provided.
