A Switched-Capacitor-Based 7-Level Self-Balancing High-Gain Inverter Employing a Single DC Source

International Transactions on Electrical Energy Systems, 2023
This paper discloses a novel switched capacitor (SC)-based 7-level inverter with a single DC source. The proposed inverter has the ability to self-balancing the voltage of the capacitor without using a closed-loop voltage balancing circuit.

Characteristics of Single-Phase Voltage-Doubler Rectifier with Balanced Capacitor Voltages

IEEJ Transactions on Industry Applications, 2001
A single-phase voltage-doubler rectifier, which has two auxiliary bidirectional switches, is studied. The proposed rectifier has the advantages that the imbalance of the voltages across the capacitors, connected in series, is minimized independent of the working conditions and the discharge of capacitors is adjusted by arranging two auxiliary ...

Printed Integrated Logic Circuits Based on Chitosan‐Gated Organic Transistors for Future Edible Systems

Advanced Functional Materials, EarlyView.
Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.
