Why DC voltage can"t step up or step down?

AC voltage only step up or step down. it is not possible to DC .what is the reason? if it is possible how?

A Boost Converter does step up DC Voltage. Here's a DIY Boost Converter -

In order for voltage to be 'stepped up/down' there needs to be a cyclical change or fluctuation/oscillation in the voltage.

If the DC voltage has that cyclical change, it can be stepped up/down.
For example, think about a DC voltage that varies between 100 vdc to 1 vdc at 60 cycles/second. A DC voltage like that can be stepped up/down by a simple transformer as is commonly used for AC power.

What are the specifications for the input and output DC voltages? There might be commercial devices available that do what you need - google dc voltage converter.

A simple DIY example would be a converter device that plugs into the 12VDC supply in an automobile and has output of household AC voltage. Then plug into that a computer/electronics power supply that produces 24VDC or 6VDC.
