Solar Inverter : Classification

The solar inverter is a critical component in a solar energy system. It performs the conversion of the variable DC output of the Photovoltaic (PV) module(s) into a clean sinusoidal 50- or 60 Hz AC current that is then applied directly to the commercial electrical grid or to a local, off-grid electrical network. Typically, communications capability is included so users can monitor the inverter and report on power and operating conditions, provide...

FPGA vs ASIC

FPGA --- Field-Programmable Gate ArrayASIC --- Application-Specified Integrated CircuitA field-programmable gate array (FPGA) can be purchased off-the-shelf and programmed by the user, whereas an application-specific integrated circuit (ASIC) is manufactured to a customer’s specification. This distinction has not changed since the dawn of both technologies.Time-to-market and configurability The configurability of an FPGA is its most priced asset....

Future wire ''NANOWIRE''

A nanowire is a nanostructure, with the diameter of the order of a nanometer (10−9 meters). Alternatively, nanowires can be defined as structures that have a thickness or diameter constrained to tens of nanometers or less and an unconstrained length. At these scales, quantum mechanical effects are important — which coined the term "quantum wires".Many different types of nanowires exist, including metallic (e.g., Ni, Pt, Au), semiconducting (e.g.,...

Wind Turbine Inspector::Helical Robotics

How do you inspect the outside of a wind turbine? Either stand on the ground and use a telescope, or set up some climbing gear and scale the tower. The first solution is imprecise and the second is expensive and dangerous. Both are time-consuming. Now there's a third option: the HR-MP20 Light Weight Magnetic Climbing Robot by Helical Robotics. This remote-controlled robot can scale a turbine tower while carrying up to 9 kg (20 lbs) of inspection...

Hydrogen Fuel Cell !!! New source of 'R'energy .

 This is the world’s first scalable Hydrogen-On-Demand process requiring minimum power input.An important characteristic of this new breakthrough is that it requires no external power input after the hydrogen-producing reaction is started, making possible, for the first time, the scale-up to high rates of hydrogen on demand (HOD) using water and scrap materials for fuel.A growing number of equipment manufacturers are planning the commercialization...

How Reactive power is generated?

If alternator is Overexcited, it will deliver reactive power with lagging currentwhile in Under excited, it absorb reactive power with leading curreentBut, it always (under or over-excited) deliver real power.WHY it needs or absorb reactive power???Actually synchronous machine maintains constant flux. When dc field current gets reduced (under excited), To strengthen main field, it absorb reactive power (draw current from ac supply mains).In reverse,...
