INTEGRATED POWER SUPPLY IMPROVING SEQUENCE

摘要

An integrated power supply is provided to improve sequence by controlling the output of the driving power according to an operation signal after outputting the standby power when a standby power circuit and a driving power circuit are integrated in a PDP power device. An integrated power device(100) includes a power converting unit(110), a standby power unit(120), a controller(130), and a driving power unit(140). The power converting unit converts commercial AC power source into a plurality of DC power sources. The standby power unit converts one of the plurality of DC power sources from the power converting unit into the previously set standby power. The controller supplies a control signal to control a power conversion operation when the standby power is inputted from the standby power unit. The driving power unit converts at least other one of DC power sources from the power converting unit into at least one driving power according to the control signal of the controller. The driving power unit includes a power converter. The power converter converts the DC power into a first driving power if the voltage level of the control signal is lower than the preset voltage level and blocks the output of the first driving power if the voltage level of the control signal is greater than the preset voltage level. The driving power unit outputs the driving power according the control signal after the standby power is outputted.
