Three Switch Three Phase Inverter With Improved DC Voltage Utilization

open access: yes, 2019
This paper proposes a new DC-AC converter with a less number of semiconductor switches and therefore gate drive and control circuit components. A salient feature of this inverter is its pure sinusoidal line-to-line voltages with no need for output filter.

A simplified space vector modulation implementation for modular multilevel converter by grouping submodules

open access: yesIET Power Electronics, 2021
Modulation strategy plays an important role in the good performance of modular multilevel converter (MMC). Since MMC has a special structure as well as a large number of submodules (SMs), it is almost impossible to apply the conventional multilevel space

High‐Spatiotemporal‐Resolution Transparent Thermoelectric Temperature Sensor Arrays Reveal Temperature‐Dependent Windows for Reversible Photothermal Neuromodulation

open access: yesAdvanced Functional Materials, EarlyView.
Thermoelectric temperature sensors are developed that directly measure heat changes during optical‐based neural stimulation with millisecond precision. The sensors reveal the temperature windows for safe reversible neural modulation: 1.4–4.5 °C enables reversible neural inhibition, while temperatures above 6.1 °C cause permanent thermal damage.

A new symmetric modular eleven‐level inverter using single and double source unit for low voltage applications with reduced number of switches

open access: yesIET Power Electronics, EarlyView., 2023
This study introduces a new modular multilevel inverter that can produce five levels of positive voltage using only six power switches and five DC voltage sources. The basic unit is composed of a single‐ and double‐source (SDS) unit. SDS reduces the number of power electronic components, such as the insulated gate bipolar transistors, freewheeling ...

Analog and Mixed Signal Verification [PDF]

open access: yes, 2008
More and more electronic systems have components that are not purely digital. Verification of such systems is a much less developed discipline than the digital equivalents and the application of formal (mathematically complete) techniques is a nascent ...

A high‐gain IΓ‐source hybrid single‐phase multilevel inverter for photovoltaic application

open access: yesIET Power Electronics, 2021
Impedance‐based step‐up converters are widely developed for photovoltaic applications due to providing single‐stage conversion, high‐efficiency, low voltage and current stresses, and high boost‐factor. An improved Γ‐source (IΓ‐source) single‐phase hybrid
