  AMS-02 recently published its lepton spectra measurement. The results show
that the positron fraction no longer increases above $\sim$200 GeV. The aim of
this work is to investigate the possibility that the excess of positron
fraction is due to pulsars. Nearby known pulsars from ATNF catalogue are
considered as a possible primary positron source of the high energy positrons.
We find that the pulsars with age $T\simeq (0.45\sim4.5)\times10^{5}$ yr and
distance $d<0.5$ kpc can explain the behavior of positron fraction of AMS-02 in
the range of high energy. We show that each of the four pulsars --- Geminga,
J1741-2054, Monogem and J0942-5552 --- is able to be a single source satisfying
all considered physical requirements. We also discuss the possibility that
these high energy $e^{\pm}$ are from multiple pulsars. The multiple pulsars
contribution predicts a positron fraction with some structures at higher
energies.
