Abstract
A power transmission system of a hybrid electric vehicle includes: an input shaft; an output shaft; first, second and third planetary gear sets; a first rotational shaft, a second rotational shaft, a third rotational shaft, a fourth rotational shaft; a fifth rotational shaft; a sixth rotational shaft; and three friction elements mutually selectively connecting rotational shafts to each other or selectively connecting the respective rotational shafts and the transmission housing such that the power transmission system of the hybrid electric vehicle can suppress conversion to an ENG mode by providing sufficient power performance at a time of wide open throttle (WOT) launching and maximally use power of an engine at a time of conversion to a first HEV mode and a third HEV mode.
