A Comparative Study of GaN HEMT and Si MOSFET-Based Active Clamp Forward Converters

Energies, 2020
Compared with conventional forward converters, active clamp forward (ACF) converters have many advantages, including lower voltage stress on the primary power devices, the ability to switch at zero voltage, reduced EMI and duty cycle operation above 50%.

Minimization of Output Voltage Ripple of Two-Phase Interleaved Buck Converter with Active Clamp

Energies, 2021
A control technique combining pulse width modulation (PWM) and pulse amplitude modulation (PAM) is presented herein to reduce the output voltage ripple of the converter as little as possible. Such a converter requires a two-stage cascaded structure.

Injection of IK1 through dynamic clamp can make all the difference in patch-clamp studies on hiPSC-derived cardiomyocytes

Frontiers in Physiology, 2023
Human-induced stem cell-derived cardiomyocytes (hiPSC-CMs) are a valuable tool for studying development, pharmacology, and (inherited) arrhythmias. Unfortunately, hiPSC-CMs are depolarized and spontaneously active, even the working cardiomyocyte subtypes

Soft-Switching Technology of Three-Phase Six-Switch PFC Rectifier

Energies, 2020
An active clamp, three-phase, six-switch power factor correction rectifier with a one-cycle controller is proposed, which can effectively suppress the reverse recovery of the reverse parallel diode of the bridge arm switch and reduce the reverse recovery

HIV-1 Gag Non-Cleavage Site PI Resistance Mutations Stabilize Protease/Gag Substrate Complexes In Silico via a Substrate-Clamp

BioChem, 2021
HIV-1 protease active site inhibitors are a key part of antiretroviral therapy, though resistance can evolve rendering therapy ineffective. Protease inhibitor resistance typically starts with primary mutations around the active site, which reduces ...

Central and peripheral analgesic active components of triterpenoid saponins from Stauntonia chinensis and their action mechanism

Frontiers in Pharmacology, 2023
Triterpenoid saponins from Stauntonia chinensis have been proven to be a potential candidate for inflammatory pain relief. Our pharmacological studies confirmed that the analgesic role of triterpenoid saponins from S.

Active clamp dual-end convertor

Electronics Letters, 1998
An active clamp dual-end convertor is proposed to achieve zero voltage switching for all switches with low voltage stress and eliminate the DC current component in the transformer. A 40 W prototype is built and the experimental results are obtained for verification.

Active-Clamp Dual-Transformer ZVS Flyback Converter

Energies
In order to upgrade the ability of the traditional flyback converter to transfer energy to the load, a dual-flyback converter with two active clamping circuits is added, using the same clamping capacitor to recover the leakage inductance energy ...
