<p>[Summary] [Object] To provide a non-isolated power-source device and an LED driving device, which can reduce power supplied to a load circuit without complicating their configurations even when either of both ends of the load circuit causes a ground fault. [Means for Settlement] A non-isolated power-source device A1 that converts input power from a DC power-source E1, a negative electrode of which is grounded to a ground line G1 into desired DC power, and supplies the converted DC power to a load circuit Y1 includes a capacitor C1 electrically connected between one end of the load circuit Y1 and the negative electrode of the DC power-source E1, and a capacitor C2 electrically connected between the other end of load circuit Y1 and the positive electrode of the DC power-source E1.</p> |
