A variable frequency drive works by changing the frequency and voltage of the power supply to an AC motor according to its load and speed requirements. The AC input is fed to a rectifier that converts it to DC. The DC output is filtered by a capacitor that forms a DC link. The DC link supplies power to an inverter that switches it on and off at ...

Simply put, energy storage is the ability to capture energy at one time for use at a later time. Storage devices can save energy in many forms (e.g., chemical, kinetic, or thermal) and convert them back to useful forms of energy like electricity. Although almost all current energy storage capacity is in the form of pumped hydro and the ...
