A reverse-blocking AlGaN/GaN metal-insulator-semiconductor high electron mobility transistor (RB-MISHEMT) is proposed and fabricated. Compared with the conventional MISHEMT ohmic drain, device features a hybrid Schottky-ohmic drain low work function Tungsten (W), based on which state-of-the-art ultralow turn-on voltage ( <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink...
This paper presents a nonisolated, high boost ratio hy-brid transformer dc–dc converter with applications for low-voltage renewable energy sources. The proposed converter utilizes a hy-brid transformer to transfer the inductive and capacitive energy simultaneously, achieving a high boost ratio with a smaller sized magnetic component. As a result of incorporating the resonant operation mode into...
Implementation of Triangular Carrier based Space Vector Modulation for3-Ø Bridge Inverter using FPGA
The Space Vector Pulse Width Modulation (SVPWM) is used for three phase bridge Inverter to produce AC output voltage of desired magnitude and frequency. The purpose of controller is to produce regulated output voltage with low distortion under varying load conditions. A triangular carrier based space vector pulse width modulation is developed in MATLAB using Xilinx block set and executed in Fie...
Introduction: Electroporation is a technique for increasing the permeability of the cell membrane to otherwise non-permeate molecules due to an external electric field. This permeability enhancement is detectable if the induced transmembrane voltage becomes greater than a critical value which depends on the pulse strength threshold. In this study, the variabil...
With the consideration of low standby leakage in nanoscale CMOS processes, a new 2×VDD-tolerant ESD clamp circuit was presented in this paper. The new ESD clamp circuit had a high-voltage-tolerant ESD detection circuit to improve the turn-on efficiency of the silicon-controlled-rectifier-based (SCRbased) ESD device. This design had been successfully verified in a 65-nm CMOS process. The leakage...
A fully-integrated 4.3-7 GHz CMOS low-voltage wideband low-noise amplifier with helical inductors has been demonstrated in this paper. The CMOS LNA, operating at a supply voltage as low as 1 V, achieves a small signal gain of 14 dB and 3-dB bandwidth from 4.3 to 7 GHz. The minimum noise figure is 2.9 dB at 6 GHz. With the benefits of helical inductors, the total effective chip size is only 0.2 mm.
In this paper, a new non-isolated transformerless high step up Dc-Dc converter with low voltage stress on the active switch for solar energy application is proposed. The converter topology is simple, which makes the control scheme simple. In this converter, only one active switch is used which makes reducing the switching power loss. The voltage gain of the proposed converter is higher than the...
In order to solve the problem of fuel pollution, the diesel fuel for power generation of marine was abandoned and shore power supply have been proposed at the historic moment. The Shore Power Supply which needs transferring 380V/50Hz to 450V/60Hz is used on shipping who need this kind of power, so effectively curbs the emissions of pollution gas into the air, and achieves the purpose of improvi...
