Abstract
A power supply device system including: a switching power supply device converting an alternating voltage to a predetermined direct current by means of a switching operation of a switching element, and supplying the direct current to a load; a control parameter generation device generating a control parameter corresponding to at least one of the alternating voltage and the direct current; and a signal transmission unit disposed between the switching power supply device and the control parameter generation device, transmitting the control parameter to the switching power supply device, wherein the switching power supply device has a control unit detecting the direct current, storing the control parameter, and generating a driving pulse for the switching element to perform the switching operation so that the direct current becomes substantially constant, based on the direct current detected and the control parameter stored.
