Why do we use 'have' in compound verbs with modal auxiliaries?

Why do we use, "might have" instead of "might had"

do have instead of do has?

can have instead of can had?

With auxiliary verbs we a lways use the infinitive (unchanging) form of the main verb: I might have, she might have, she might go, we might see I should have, she should have, she should dance, we might eat I can have, she can have, you can see, they can find etc.

With auxiliary verbs we always use the infinitive (unchanging) form of the main verb:

I might have, she might have, she might go, we might see
I should have, she should have, she should dance, we might eat
I can have, she can have, you can see, they can find
etc.

Thanks a lot Mister Micawber. This is something I've just naturally used but never really have known the explanation behind it.
