Verbs in English can be active or passive. Passive verbs are expressed with a form of to be followed by the past participle form of the verb.
Pretty much all tenses and aspects can work in active or passive form.
So to X is the infinitive, and to be X'ed is the passive form of the infinitive.
I didn't want to drive to the store.
I didn't want to be driven to the store by anyone.
Why use passive voice? Passive voice can be used to deflect attention from who is doing something, or express an action when we really don't know, don't care, or want to say who is doing something. It can also change the "direction" of a verb in the sense of who is doing what to whom.
The car was destroyed. (We don't want to say who did it, or it doesn't matter who did it.)
The car was destroyed by an employee. (Putting focus on the event rather than who did it.)
An employee destroyed the car (Sounds more like we are blaming the employee here.)
The management asks to control the funds to request from the department. (Management wants to control what we ask to others.)
The management asks to control the funds to be requested from the department. (Management wants to control what others ask to us.)
