Special Issue Information

Dear Colleagues,

Within the last decade, supercapacitor technology has developed rapidly with some of the newer families reaching the energy density of rechargeable lead-acid battery chemistry. As per IDTechEx market reports, by the year 2041, supercapacitor business will be a multi-billion-dollar business, taking 10% of the battery sales market. The rapidly growing electric vehicle industry is one of the main users of supercapacitors, due to their long life, which is several orders higher than the lifecycle of rechargeable batteries. High power density and lesser environmental impact are other attractive characteristics of new supercapacitor families.

Traditional applications of supercapacitors include the use of them as an energy storage device, in all types of electronic systems. In this regard, they can replace electrochemical batteries, or they can be used in hybrid form with traditional batteries for better overall performance. A non-traditional application domain of supercapacitors is the supercapacitor-based long time-constant circuits which could help in high performance power converters and protection systems.

We invite prospective authors to submit papers to this Special Issue of Electronics, before the deadline of 30 October 2021.

The following is a tentative guideline to potential application areas:

Automotive applications;

Renewable energy applications;

Avionics;

Telecommunications applications;

Cellular phones;

Memory backup systems;

UPS and power quality enhancement systems;

Battery–supercapacitor hybrids;

Semiconductor fabrication (for system on chip applications);

Consumer electronics;

Tools.

Additionally, we are happy to invite a limited number of review papers on device technology and supercapacitor fabrication.

From the first patent of supercapacitors, the industry has experienced the commercialization of supercapacitors happening rapidly after the year 2000. Within the last 5 years, the electronics industry has gained access to at least four different types of commercially available supercapacitor families, namely, electrochemical double layer capacitors (EDLCs), hybrid supercapacitors, battery capacitors and pseudo capacitors. Over the same period after year 2000, there has been huge developments in the electrochemistry of supercapacitors based on new materials such as graphene and mechanisms such as tailoring pore sizes for electrolyte ion exchange to increase volumetric energy density. This paper compares the characteristics of three different types of supercapacitors for large energy applications and how supercapacitors can be useful in future DC-DC converters in renewable and micro-grid applications.

Based on the discovery of the surge absorption capability of supercapacitors, a transient protector named supercapacitor-assisted surge absorber (SCASA) was designed and implemented in a commercial device. Despite its simplicity, the circuit topology consisted of a coupled inductor wound around a specially selected magnetic core. This paper elucidates the design aspects of SCASA coupled-inductor topologies with a special focus on the magnetic action of core windings during transient propagation. The non-ideal operation of the SCASA transformer was studied based on a semi-empirical approach with predictions made by using magnetizing and leakage permeances. The toroidal flux distribution through the transformer was also determined for a 6 kV/3 kA combinational surge, and these findings were validated by using a lightning surge simulator. In predicting the possible effects of magnetic saturation, the hysteresis properties of different powdered-iron and ferrite core types were considered to select the optimal design for surge absorption. The test results presented in this research revealed that X-Flux powdered-iron toroid and air-gapped EER ferrite yielded exceptional performance with ∼10% and ∼20% lower load–voltage clamping compared to that of the existing Kool μu design. These prototypes further demonstrated a remarkable surge endurance, withstanding over 250 consecutive transients. This paper also covers details of three-winding design optimizations of SCASA and LTSpice simulations under the IEC 61000/IEEE C62.45 standard transient conditions. Full article

All electrical and electronic devices require access to a suitable energy source. In a portable electronic product, such as a cell phone, an energy storage unit drives a complex array of power conversion stages to generate multiple DC voltage rails required. To optimize the overall end-to-end efficiency, these internal power conversions should waste minimal energy and deliver more to the electronic modules. Capacitors are one of the main component families used in electronics, to store and deliver electric charges. Supercapacitors, so called because they provide over a million-fold increase in capacitance relative to a traditional capacitor of the same volume, are enabling a paradigm shift in the design of power electronic converter circuits. Here we show that supercapacitors could function as a lossless voltage-dropping element in the power conversion stages, thereby significantly increasing the power conversion stage efficiency. This approach has numerous secondary benefits: it improves continuity of the supply, suppresses voltage surges, allows the voltage regulation to be electromagnetically silent, and simplifies the design of voltage regulators. The use of supercapacitors allows the development of a novel loss-circumvention theory with applicability to a wide range of supercapacitor-assisted (SCA) techniques. These include low-dropout regulators, transient surge absorbers, LED lighting for DC microgrids, and rapid energy transfer for water heating. Full article
