摘要： A standby power supply apparatus is provided in which a supply voltage of the standby power source, supplied before electronic apparatuses such as TVs or video players are switched on, is reduced by half to sharply reduce the consumption of the standby electric power. According to the standby power supply apparatus, it is possible to reduce by half the electric power loss due to switching the standby power converter controlling the standby electric power of the power supply apparatus on and off. Additionally, the standby electric power can be sharply reduced without an additional increase in manufacturing costs of the power supply apparatus.

摘要： A display apparatus, a power supply apparatus and a power supply method thereof are provided. The display apparatus includes: a signal processor which processes an image signal; a display unit which displays thereon an image corresponding to the processed image signal; and a power supply unit which receives an input of AC power and supplies operating power to the display unit. The power supply unit includes a discharging circuit unit which discharges a remaining voltage of the power supply unit if the input of the AC power is suspended, and does not discharge the voltage if the AC power is input. Accordingly, a remaining voltage from a power supply unit is effectively removed if an input of AC power is suspended, and power consumption does not occur if the AC power is input.
