IEEE transactions on industrial electronics (1982. Print), 2020
In this letter, we introduce a simple turn-on snubber for the conventional bidirectional converter. This snubber notably reduces the current reduction rate of the converter main diodes at turn-off.

A Low-Reverse-Recovery-Charge Superjunction MOSFET With P-Base and N-Pillar Schottky Contacts
IEEE Transactions on Electron Devices, 2020A superjunction metal-oxide-semiconductor field-effect transistor (SJ-MOSFET) with P-base and N-pillar Schottky contacts is proposed and investigated in this article. The dual Schottky contacts form a p-type Schottky diode and an n-type Schottky diode on

Evolution of reverse recovery in trench MOSFETs
International Symposium on Power Semiconductor Devices and IC's, 2020The interaction between the reverse recovery charge and the output charge in trench power MOSFETs is discussed. As the trade-off between the on-resistance and the gate charge improves, the output capacitance has more impact on the reverse recovery losses.

β-Xylosidase Recovery by Reversed Micelles
Applied Biochemistry and Biotechnology, 2000β-Xylosidase, an enzyme produced by Penicillium janthinellum fungus, was prepurified by fractionated precipitation with ethanol and extracted by reversed micelles of N-benzyl-N-dodecyl-N-bis(2-hydroxyethyl) ammonium chloride (BDBAC) cationic surfactant.

Reverse recovery failure modes in modern fast recovery diodes
2000 22nd International Conference on Microelectronics. Proceedings (Cat. No.00TH8400), 2002In this paper, reverse recovery failure modes in modern fast power diodes are investigated. By the aid of semiconductor device simulation tools, a better view is obtained for the physical process, and operating conditions at which both diode snappy recovery and dynamic avalanching phenomenas occur during the recovery period in modern high frequency ...

Energy recovery circuits using reversible and partially reversible logic
IEEE Transactions on Circuits and Systems I: Fundamental Theory and Applications, 1996This paper presents a new family of logic gates for low energy computing using pulsed power CMOS logic. The logic gates use the principles of adiabatic-switching and results show that in typical cases 90% of the energy can be recovered with operating frequency around 1 MHz.

Sub-nanosecond Reverse Recovery Measurement for ESD Devices
IEEE International Reliability Physics Symposium, 2020A method to measure sub-nanosecond reverse recovery in wafer-level test structures is presented. The setup uses a transmission line pulse generator with a time-domain through connection to measure the device-under-test current.

Desalination, 1990
Abstract As a means to minimize or eliminate brine disposal problems, high recovery RO must be accompanied by pre- or post-treatment to avoid scale precipitation, almost entirely by CaSO4. All such methods will add to water cost. However, rigorous comparison must be made with the costs and constraints of brine disposal at recoveries low enough not ...
