* Correspondig author AbstractA high power three-phase rectifier that does not require a passive phase shifter (e.g. polyphase multi-winding transformer) was studied analytically and by simulation. The proposed rectifier includes 6 uni-directional switches and 24 diodes that are used to realize two three-phase bridges. The outputs of the bridges are connected in parallel via two blocking reacto...

A novel three-phase phase-locked loop solution is proposed based on D-Q transformation aiming at the AC-DC rectifier with high efficiency and high power factor. The phase-locked loop is implemented digitally using the Xilinx blockset integrated with Matlab/Simulink. The three-phase digital phase-locked loop (TDPLL) is elaborately designed with the parameters defined in detail. The AC-DC convert...

Development of energy harvesting and wireless power transfer have emerged batteryless and non-contact energy transfer. For optimum power transfer between antenna and the rectifier circuit, impedance of the antenna and rectifier should be match. This paper describes the design and implementation of the 7-stage multiplier in energy harvesting. A Modified dickson configuration is chosen, consists ...

For Silicon devices, the forward voltage drop of the pn-junction rectifier can not be reduced below about 0.8 volts even if the device is not required to block higher reverse voltage. In the case of the output rectifiers used in power supplies for computers and telecommunications, this voltage drop is a large fraction of the output voltage of 5V or less. This results in a loss in the power supp...

The molecular targets and neural circuits that underlie general anesthesia are not fully elucidated. Here, we directly demonstrate that Kv1-family (Shaker-related) delayed rectifier K(+) channels in the central medial thalamic nucleus (CMT) are important targets for volatile anesthetics. The modulation of Kv1 channels by volatiles is network specific as microinfusion of ShK, a potent inhibitor ...

In hydrogen production, AC-DC rectifiers must provide a high current and low voltage to the production load. This paper focuses on efficient performance elimination of output ripple in these rectifiers. Unfortunately, efforts reduce often lead lower efficiency, causing contradiction. To address this issue, low-ripple high-efficiency rectifier with an auxiliary compensator is proposed paper. The...

By using an RC network to add slow negative feedback to the inverting Schmitt trigger, a relaxation oscillator is formed. Precision rectifier, OpAmp Precisio...

This paper presents a rectifier for passive UHF RFID tags with high power conversion efficiency (PCE) over a wide incident power range under the influence of mismatch between tag antenna and chip, which benefits read and write sensitivities simultaneously. Fabricated with 0.13 μm CMOS technology, the RF frontend adopting this rectifier achieves PCE higher than 25% with incident power from −19.2...

We demonstrated nanoscale solid-state thermal rectification. High-thermal-conductivity carbon and boron nitride nanotubes were mass-loaded externally and inhomogeneously with heavy molecules. The resulting nanoscale system yields asymmetric axial thermal conductance with greater heat flow in the direction of decreasing mass density. The effect cannot be explained by ordinary perturbative wave t...
