A convergence type power supply device includes a supply circuit and a filter circuit, and both circuits receive a rectified pulse DC power, and the supply circuit supplies the pulse DC power to a load directly when the filter circuit is charged, and the voltage of the pulse DC power becomes higher after the filter circuit is charged, and the filter circuit filters the pulse voltage to supply a filter DC to the load, so as to achieve the effect of enhancing the power factor.
