Design of a Modified-Bridge Circuit with a Master-Slave Input Supply Mechanism for Ozone-Driven System Applications

This study proposes a design of a modified-bridge circuit with a master–slave input supply mechanism for ozone-driven system applications. Because the single-source supply design is becoming the mainstream choice in the existing ozone-driven systems, the input supply reliability of the ozone-driven system is crucial. Therefore, this proposed design involves a modified-bridge circuit combined with inductors and transistors, which can be augmented with the energy storage device as a backup source to improve the reliability of the input supply for the ozone-driven system. In addition, considering that the original source directly connected to DC BUS can re-charge the energy storage device, the energy recycling operation mode is designed in this proposed system to extend the duration of the energy storage device, which improves the supply reliability of the ozone-driven system further. To validate this proposed system, both model formulation and hardware realization are assessed through different test scenarios. Experimental outcomes of these tests confirm the practicality of the proposed design.

An Effective Designing of Supercapacitor Mitigating Self-Discharge

Supercapacitor is a kind of effective energy storage device with merits such as high power density, long cycling life and so on, but their application is limited nowadays compared to the application of batteries. One important restriction is because of the serious self-discharge in supercapacitors, and how to conquer the self-discharge problem is an important issue. In this article we propose an effective way to reduce self-discharge of the supercapacitor by carefully designing of activated carbon (ACs) electrodes and water-in salt electrolyte. The electrochemical characterization shows that our supercapacitor can have the ability to reduce self-discharge.
