Capacitors & Condensers

In the recent past battery and fuel cell technology are undergoing rapid advancements. The supercapacitor technology has to overcome these devices in economy, performance and utility to make itself a viable option. Thus the challenges faced by this technology are unique.

Electronic devices have become an extension of our body parts. They play a vital role in helping humans condition the environment according to their suitability. In this article, attention will be focused on the basic electronics components… - Sandeep Banerjee, Nishtha Verma

In order to tap into the nanotechnology solution to electricity generation, transmission, storage and distribution, basic requirement is to have the complete knowledge of power system, and according to the papers regarding nanotechnology appropriate solutions can be found to the problems facing in power system…- Dr. Vikramaditya Dave, Er.

Power factor is the ratio between the KW and the KVA drawn by an electrical load. Where the KW is real power to load and KVA is the apparent load power. It is the measurement how an electrical equipment getting current in actual. A load with power factor of 0.85, results much higher losses in supply system and consumer has to pay higher bill… - Anuraj Kumar

Supercapacitors and ultracapacitors are one and the same. The difference in the nomenclature can be attributed to the Europeans and the Americans. Europeans call the same device supercapacitor while the Americans know it as ultracapacitors... - Dr P B Karandikar, Dr N R Kulkarni,  Seema Mathew

Capacitors mostly start getting damaged due to repeated voltage fluctuations (exposure to higher voltage)…

Supercapacitor also known as electric double layer capacitor is emerging as a new energy storage device. Due to its high power density, wide thermal operating range, low cost, and long cycle life, it bridges the gap between battery and conventional capacitor. However, it has lower energy density than batteries. Electrode material plays a key role for improving the capacitance, and hence energy density of supercapacitor. In leading research and development organisations in the world, research works are going on in search of new electrode materials for improving the capacitance of the supercapacitors. This article presents a new approach to synthesise activated carbon from leaves of trees as an electrode material for supercapacitors. Activated carbon obtained by such process can be cost effective and also environmental friendly...- Gaurav Shekhar,Ashutosh Phatak, Dr PB Karandikar,Prof Swati Shirish More

In previous publications, authors have reported about the performance of the single-phase inverter topology based on controlled charging of the capacitor. The dynamic performance was not available. This article presents the dynamic performance of the inverter for various types of load, which includes leading, lagging and unity power factor, and analysis for 'total harmonic distortion' has been included... - K.Vijayakumar, S.Kannan and S.Ponnayira Sundaravel

The most common solution to harmonic problems involves the application of harmonic filters. Capacitors and the system short-circuit impedance combine to create resonances that can magnify harmonic levels to well above accepted limits. What is the solution? - Dr L Ashok Kumar

Ultracapacitors have large energy densities – up to 1/10th of battery or even more, but their strengths lie in high power delivery... - R P Deshpande
