Summary: The study demonstrates the 250 degrees C operation of a diamond-based monolithic bidirectional switch, with a normally-ON double gate deep depletion MOSFET. By controlling the channel conductivity with both gates separately, the switch successfully achieves clear ON and OFF states. This first proof of concept offers a reverse conducting and reverse blocking diamond MOSFET, with only one drift region layer.

Summary: Existing line commutated converter (LCC)-based high-voltage dc (HVdc) systems require a large amount of reactive power and costly reactive power compensation equipment. This letter proposes a novel operation of a hybrid LCC based on integrated gate commutated thyristor (IGCT) to achieve LCC with ultra-low reactive power (LR-LCC), utilizing IGCT's active blocking and bidirectional voltage withstanding capability. The LR-LCC almost eliminates the system's extinguishing angle and achieves a close-to-unity power factor. This novel LR-LCC can significantly reduce the manufacturing cost and volume of reactive power compensation equipment for HVdc application.

Summary: This article proposes a probabilistic multiobjective evolutionary algorithm (MOEA/D) method with a risk-based decision-making strategy, utilizing scenario-based technique to generate a stochastic model of the hybrid energy system and proposing a probabilistic penalty-based boundary intersection (PBI) with gradient descent differential evolution (GDDE) algorithm to search for the optimal scheme. The Markov inequality is employed to deduce a proper interval of the uncertainty budget, and a fuzzy grid technique is proposed for choosing the best scheme for real-world applications. The experimental results demonstrate that the probabilistic adjustable parameters can effectively control the uncertainty budget and reduce the risk probability, while the MOEA/D-GDDE can significantly improve optimization efficiency.

Summary: This paper proposes a novel algorithm called HOSS algorithm to solve the optimal operation problem in energy management of the hybrid electric vehicle (HEV).

Summary: This article presents a monolithic GaN-based driver that reduces reverse conduction and improves driving capability and switching frequency by using the diode-emulated technique with a meta-stable fast comparator. Additionally, an active bootstrap controller with a fast discharge loop is utilized to reduce parasitic effects and minimize gate-ringing during turn-on/turn-off. Experimental results demonstrate that the GaN-based monolithic driver achieves high operating frequency and efficiency in energy conversion.
