New modulation scheme for bidirectional qZS modular multi-level converters
The Journal of Engineering, 2019 This study proposes a dedicated modulation scheme for a bidirectional quasi-Z-source (qZS) modular multi-level converter. The operation principle and a suitable pulse-width modulation method are proposed.

Computer-aided simulation of power MOSFET switch-mode convertors
Electronics Letters, 1984 A computer-aided modelling procedure for power MOSFET switching convertors is reported. Results show dynamic turn-on and turn-off device waveforms, peak stresses, switching trajectory and transient switching losses. Excellent agreement is demonstrated between predicted and measured switching characteristics on an experimental high-frequency high ...

FEBS Open Bio, EarlyView.Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

FEBS Open Bio, EarlyView.ZFAS1 is a lncRNA promoting cell proliferation and migration, exhibiting high expression in various cancers. It is conserved, widely expressed, and produces multiple splice variants with unclear roles. We identified several splice variants in hepatocyte models, and found that inhibiting or suppressing regulators of the unfolded protein response (PERK ...

FEBS Open Bio, EarlyView.This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Non-isolated resonant link DC–DC converter for use with GaN devices
The Journal of Engineering, 2019 As new wide band-gap (WBG) devices are developed and improved, new topologies and control schemes are required to take advantage of the ultra-fast switching turn on/off speeds that are now available, without the limitations of switching losses and ...
