High-voltage switchgear refers to electrical equipment operating within a voltage range of 3.6 kV to 550 kV, used in power generation, transmission, distribution, energy conversion, and consumption systems for switching, control, or protection purposes. It primarily includes high-voltage circuit breakers, high-voltage disconnectors and earthing switches, high-voltage load switches, high-voltage auto-reclosers and sectionalizers, high-voltage operating mechanisms, high-voltage explosion-proof swi

What is SST?SST stands for Solid-State Transformer, also known as Power Electronic Transformer (PET). From the perspective of power transmission, a typical SST connects to a 10 kV AC grid on the primary side and outputs approximately 800 V DC on the secondary side. The power conversion process generally involves two stages: AC-to-DC and DC-to-DC (step-down). When the output is used for individual equipment or integrated into servers, an additional stage to step down from 800 V to 48 V is require

With the increasing demand for transparent/flexible displays, healthcare sensors, and robotics, there is a need to advance the development of thin-film transistors (TFTs) manufacturing and large-scale circuits. This paper has proposed an IGZO-TFT-PDK to aid the educators and research community to explore the circuit design space of dual-gate IGZO-TFT devices. To solve the tensile force-induced current variation problem in IGZO-TFT devices, an omni-directional device and its layout template with
