hi,there is 27 volt ( input voltage ) and i need to have 100 volt output . anyone can help me how to do that ?
i dont have power supply, i wish to convert 27v input to 100v 1A outputDo you already have a power supply of >100V, or do you wish to convert the 27V input to 100V output? At how much current?
Nor what frequency, nor what accuracy!All this talk about converting a voltage - but nobody has said, or asked, if it's AC or DC voltage you want to convert.
So true. But people sometimes use terms incorrectly. Just because WE know what an amplifier is - doesn't mean all people know. To me - an amplifier is something most often used with audio equipment. However, it can also be used in data transmission or other applications where a low current signal needs to be boosted. But a "Voltage Amplifier"? Well, it's possible we're still talking audio or some other frequency such as a radio transmitter. But if I look purely at the term "Voltage" I'm assuming (a dangerous thing to do) is changing one voltage into another.a great deal of explanation is required.
Make that 27V @ 2.05A to allow for 90% conversion efficiency.max range of supplier is 27V with 1.8Amp.
yes, but i want to know is there any circuit (with transistor and op-amp) that i can achieve this goal . webench just helped to find dc-dc convertor.So, Did TI's Webench give you a satisfactory solution?
The answer is No.yes, but i want to know is there any circuit (with transistor and op-amp) that i can achieve this goal
The only way this would be possible is if you already have a +100V power supply. Amplifiers do not do power conversion; they use an existing supply to make a "copy" of low level signals. Only a DC-DC converter can do what you have asked.yes, but i want to know is there any circuit (with transistor and op-amp) that i can achieve this goal . webench just helped to find dc-dc convertor.
Certainly a boosting converter can be created with an op-amp oscillator driving a transistor amplifier stage, and it can even provide a DC output if rectification and filtering are provided. BUT it will not be as efficient as a well designed boost type power converter, which is one form of a switching mode power supply. An examination of the various switching supply configurations is what I suggest. It will not be very efficient, either, and it weill not provide good regulation of the output voltage. It is not a direct arrangement, but rather a series of stages. Not at all what is asked for. But it can be done.The answer is No.
You need a DC to DC Boost converter.
