A power apparatus includes a compensator which is capable of enabling phase to lead as the frequency increases, even if gain increases, as shown in a Bode diagram, so as to operate stably. The power apparatus includes a power converter for controlling a voltage from a power source and supplying it to a load, a smoothing circuit which is connected between the power converter and the load, and a controller for controlling the power converter, wherein the controller is formed of an amplifier, first to seventh (or eighth) resistors, and first and second capacitors, arranged to provide specific transfer functions.
