Power for the boost converter can come from any suitable DC source, such as , , , and DC . A process that changes one DC voltage to a different DC voltage is called DC to DC conversion. A boost converter is a with an output voltage greater than the source voltage. A boost converter is sometimes called a step-up converter since it "steps up" the source voltage. Since power () , the output c.

A grid-tie inverter converts (DC) into an (AC) suitable for injecting into an , at the same voltage and frequency of that power grid. Grid-tie inverters are used between local electrical power generators: , , , and the grid. To inject electrical power efficiently and safely into the grid, grid-tie inverters must accurately ma.

An inverter converts the DC electricity from sources such as or to AC electricity. The electricity can be at any required voltage; in particular it can operate AC equipment designed for mains operation, or rectified to produce DC at any desired voltage. An (UPS) uses batteries and an inverter to suppl.
