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.

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.

A supercapacitor (SC), also called an ultracapacitor, is a high-capacity , with a value much higher than solid-state capacitors but with lower limits. It bridges the gap between and . It typically stores 10 to 100 times more or than electrolytic capacitors, can accept and deliver charge much faster than batteries, and tolerates many more

Solar power needs to be converted from (DC, as it is generated from the panel) to (AC) to be injected into the power grid. Since solar panels generate peak power only for few hours each day, and DC to AC converters are expensive, the converters are usually sized to be smaller than the peak DC power of the panels. This means that for some hours each day the peaks are "" and the extra energy is lost. This has very little impact on the total e.
