Hello, would you help me with this sentence?

Output voltage is controlled three times of the voltage (which is) applied to the terminal.

Do you understand this sentence?
Do I have to add a preposition "in" or "to" or other between controlled and three times?

Thank you

I really don't understand it. But as your sentence appears passive (English sounds better where its active, that is, SVO) it probably needs a preposition. Thus we have "Output voltage is controlled (by) three times of the voltage, which is applied to the terminal.
However, that still doesn't sound right to me. It could be, though, as it's a matter of physics, with whose jargon I am unfamiliar.

P.S. Are you sure the verb "control" suits you in this case?

Yes...it'd better if I write it as
Output voltage becomes x3 of the voltage applied to the terminal by controlling.

But I want to say "output voltage is controlled" first. What will it be?
Sorry for bothering you by my request

Hi. You didn't provide context which makes it more difficult to help. Being said, I can only guess that you might be interested in this:

Okay, you have "Output voltage becomes (three times) the voltage applied to the terminal by controlling (it)," and you want to rearrange the elements of the sentence in order that it start with "Output voltage is controlled." All right, written your way, we would get something like the following: "Output voltage is controlled, whereupon it becomes three times the voltage applied to it." While this is the construction you sought, I must admit that it is syntactically poor, and perhaps grammatically incorrect. Look, if you want to passively put the intransitive verb at the beginning of the sentence, you had better start the sentence with the conjunction "when," which in this instance would function to "indicate a time frame during which something takes place, or an instant, action, or occurrence when something begins or is done" ( Merriam-Webster's 11th Collegiate Dictionary). Thus we would have, "When output voltage is controlled, it becomes three times the voltage applied to it." You're probably thinking that the "whereupon" I lifted from the preceding sentence had already served this function; if you are you're right. However, when you start the sentence in the passive without the fuction word for time and occurence (when, on, upon, etc.), you leave the reader anticipating a preposition followed by a subject, which you can't do in this case since the verb "control" is intransitive. In close, you should use one of the following three sentences, none of which deviates very much from that for which you're shooting:

(1) Output voltage becomes three times the voltage applied to the terminal by controlling it.

(2) When output voltage is controlled, it becomes three times the voltage applied to it.

(3) When you control output voltage, it becomes three times the voltage applied to it.

Regards,

John
