Kvitova made the stronger start at the National Tennis Center, as the Czech player claimed a key break of serve to take the opening set 6-4.
The match remained close as her Australian opponent hit back in the second to force the match into a decider.
Barty maintained the momentum to complete the comeback, with the world number one triumphing 4-6, 6-4, 6-3.
She will now face Kiki Bertens, with the Dutch player defeating tournament third seed Elina Svitolina of Ukraine.
Bertens claimed the opening set on a tie-break, but dominated the second to win 7-6, 6-2.
