The two answers below from 2 different people could each be correct depending on what additional things you have available and what your intended purpose for the final voltage is.
The first answer, suggesting use of a 741 operational amplifier(op amp) would be the approach to use if your 30 volts DC were a low current signal which you wanted to transform into a specific higher voltage but still low current signal. In order to do this, you would require pre-existing supply rail voltages greater than or equal to your desired final voltage. This is one step that an electrical engineer or student may take in designing a product or experiment.
The more likely scenario is that an individual wants to run some device designed for household 110 volt AC mains power off of 2- 12 volt DC batteries. When connected in series 2- 12 volt batteries typically produce around 30 volts. Since the original question implied that the device could run on either 110 VAC or 110 VDC the device is either: A universal motor of some kind such as an angle grinder; Or an electronic device such as some laptop computers designed for worldwide use which accept a wide range of power sources. In that case, the way to supply sufficient amounts of current at the higher voltage, without requiring a pre-existing higher voltage is to employ an inverter rated for at least the power demand of the device to be run. The inverter increases the output voltage by drawing a much larger input current. So be sure your battery has sufficient capacity.
By using suitable amplifiers like Ic 741 we can to step up the dc voltages.
Sorry, no. An i.c. is totally inappropriate.
You need a circuit called an inverter.
In view of the fact that you have to ask the question in the first place, I would suggest that the complexity of an inverter is too high for you to condsider making one yourself.
They are available, but the closest thing you are likely to find is one which runs from 24Vdc.

How do you convert 1.5 volts AC to 100 watts AC?
P = V x A, POWER (watts) = VOLTS times AMPS But 1.5V AC is not a normal output
Is the maximum voltage in an ac circuit when the rms voltage is 110 volts?
It depends on the equipment. The power supplies on most devices can only handle a specific voltage and still work properly. Some, for instance some cell-phone chargers, can handle a range of voltages, say from 110 to 240, which lets them operate in both the States and the UK (where the standard home/office voltage is 230 Volts). Check the label on the back of the device; it will usually show the operating voltage required. Asking the maximum voltage for 110 equipment is valid. 110 means AC voltage that averages 110 volts as it swings above and below 0 volts. The label on a device typically will not tell you the maximum voltage it can withstand if it is plugged into a U.S. 110 volts AC outlet. U.S. houses are wired with 2 hot wires (each 120 Volts AC but opposite of each other) and a neutral wire (0 volts). That way electrical outlets can be wired for 120 Volts AC if they use a hot wire and the neutral wire... or 240 volts AC if they use both of the hot wires. If the neutral line goes bad then the 120 volts AC outlet floats anywhere from 0 volts to 240 volts. I have been in a house when this occurred (the neutral corroded on the transformer that fed several houses). Supplying too high a voltage burned out an air conditioner, a refrigerator, and an incandescent bulb actually burst, scattering glass close to my wife. The air conditioner threw out a lot of smoke so there was a danger of fire. In the U.S. a typical 120 volts AC circuit often has a higher voltage. I have seen specifications and codes that put an upper allowable voltage at 120 volts AC, 137.5 volts AC, and 150 volts AC. Every electrical device has different limits but I would not subject anything built for 120 volts AC to voltages higher than 132 Volts AC unless I had specific knowledge that the device could handle the higher voltage.
What is the formula to convert 240 volt to 12 volts?
If it is AC then you don't need a formula, you just need a transformer.
Rms value defination?
Because alternating current (AC) voltage varies over time, to the positive and negative, an actual AC voltage measurement will not be the same as a DC voltage measurement. For example: 5 volts DC is 5 volts constantly, viewed over time. The average voltage is 5 volts. 5 volts AC (from zero to peak) is not actually 5 volts constantly, but varies between 5 volts and 0 volts over time. The average voltage will not be 5 volts. Using RMS AC values is designed to make AC and DC measurements equivalent, for example 5 volts DC and 5 volts RMS AC are almost identical.
Is 12 volts peak to peak the same as 12 volts ac?
No. 12 volts peak to peak would be 6 in the positive polarity and 6 negative polarity. Simply saying 12 volts AC would be 12 volts in each polarity or 24 volts peak to peak
How do you convert 110 volts into 30 volts?
AC - use a step-down transformer. DC - simplest but most wasteful, use a dropping resistor (in series). Otherwise it is costly.
Can the 85-Watt Foreign Travel AC Converter convert 220 volts to 110 volts?
Yes, that's exactly what it's designed to do.
Is there a converter that will turn car DC to use on microwave oven?
Yep. It is called an inverter to convert 12 volts to 110 volts AC. Get one that will supply the amp needed for the microwave.
Do you have 220v or 110v?
An ipod nano is 110 volts. Why, because our regular outlets are 120 volts AC.
How do you convert 1.5 volts AC to 100 watts AC?
P = V x A, POWER (watts) = VOLTS times AMPS But 1.5V AC is not a normal output
When i plugged 110 volts wii into 220 volts socket smoke came out of the ac adaptor did i damage the console?
No way of telling, but you certainly fried the AC adaptor.
Can you just replace the 110 volts AC adapter if it was accidentally plugged in 220 volts?
no probably not , you might have overloaded it with to much power
Convert 600 dc volts into ac volts?
This action takes inverter equipment that is explained in the link below.
How do you convert 24volts to 12 volts?
If you want to convert 24v AC into 12v Ac, it's simple. Just get a transformer to convert 24 volts into 12 volts. This is called a stepdown transformer. If you want to convert 24v DC into 12v DC, it's more complicated. First you have to change the 24v DC into 24v AC by a switching converter that changes DC into AC. Then you would use a stepdown transformer as in the former example. Once the 24v AC is converted to 12v AC, then you use a rectifier bridge to change the 12v AC into 12v DC.
What are examples of voltage?
220 volts, 110 volts, 440 volts, 400 volts, AC or DC voltage. High voltage like - 220 KV, 400 KV, etc
Does China use 220 or 110?
China uses 220 Volts AC for household electricity
How do you convert 5 volts into 12 volts?
If it is AC voltages you need to convert, you need to find a transformer to do this job. Without knowing the application it is hard to guess what you are trying to do.
