Energy storage technologies can be employed to store the useful energy from renewable resources according to their availability and can be made use in future. They have the added benefits of improving stability, power quality, and reliability of supply...
This will form part of the portfolio led by Mark Kempton, the company's Business Unit Director for Semiconductor Devices.
The selection of over-current protection devices such as fuses and circuit breakers is made more complicated when high inrush currents must be tolerated. The over-current protection must react quickly to overload or short circuit faults but must not interrupt the circuit when the (usually harmless) inrush current flows…
Mitsubishi Electric Corporation revealed that it has developed a 6.5 kV full silicon carbide (SiC) power semiconductor module that is believed to offer the world's highest power density (calculated from rated voltage and current) among power semiconductor modules rated from 1.7 kV to 6.5 kV.
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.

Sujit Kumar
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
Reduction of heat transfer from outside to inside of a building lowers the cost of (electricity) cooling during summer days...
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)…
Due to the interdisciplinary nature of NRAI technologies, advancements in future industrial and space systems will experience an exponential growth cycle like that is observed in the human genome... - P M Menghal
Emerging technologies of High Temperature Superconductors (HTSrs) have an enormous potential for improving capacity of underground and overhead power T&D systems, motors, generators and power plants – because higher Jc and zero resistance of HTSrs reduce losses and can replace conventional conductors... - Hambir Singh
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
