    摘要: A method of controlling a temperature of a fuser in an image forming apparatus includes generating a power capsule including a soft start period in which a power supply is gradually increased to improve a flicker characteristic, a full turn on period in which the power supply is maximum, and a soft end period in which the power supply is gradually decreased to improve the flicker characteristic. The power capsule is profiled to supply a constant amount of power and to satisfy a predefined requirement for flicker and harmonic characteristics of an image forming apparatus with respect to the fuser in the soft start period, the full turn on period, and the soft end period. The method includes detecting the temperature of the fuser and controlling the temperature of the fuser by performing a power control operation corresponding to the power capsule according to a temperature variation of the detected temperature of the fuser with respect to a reference temperature of the fuser.

    摘要: An apparatus and method for controlling the power supplied to a fixing unit are provided. The apparatus includes a voltage detector detecting a voltage of input power supplied to heat at least one heating lamp, a synch signal generator generating a synch signal in response to the detected voltage, a switching unit switching a supply path of the input power to be applied to the at least one heating lamp, and a controller having table information of temporal duty level values of the input power that is initially supplied, and outputting a control signal for controlling a switching operation of the switching unit using the generated synch signal and the table information, wherein the switching unit performs the switching operation corresponding to the control signal. Accordingly, by sequentially increasing the input power for initial heating of the heating lamps, flickering and harmonic characteristics of a display device can be reduced, and by setting the duty level values to supply the maximum input power within a certain time, an initial heating time of the heating lamps can be minimized.

    摘要: A power converter controlling apparatus that can prevent burnout caused by overcurrent and/or overvoltage generated by low power index operation or output short circuit in a high frequency power converter employing a digital controlling method, and a method thereof. The power converter controlling apparatus includes a digital controller which outputs a gate signal for controlling intermittent operation of a predetermined switch based on inputted control data, a detector which generates a detection signal in response to generation of overcurrent and/or overvoltage, and a registration maintenance unit for maintaining a state where the output of the gate signal is shut off, when the detection signal is generated.
