A typical power inverter device or circuit requires a stable DC power source capable of supplying enough current for the intended power demands of the system. The input voltage depends on the design and purpose of the inverter. Examples include: • 12 V DC, for smaller consumer and commercial inverters that typically run fro.

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.
