Abstract: Disclosed is a display apparatus capable of preventing and/or reducing overheating of driving switches due to a malfunction during varying of a driving voltage. The display apparatus includes: a light emitting diode; a power supply configured to apply a driving voltage to the light emitting diode; a driving switch configured to control the driving current of the light emitting diode; a voltage sensor configured to detect the driving voltage; and a driving controller configured to control the driving switch so that the driving current of the light emitting diode follows a current reference. The driving controller may be configured, based on the driving voltage detected by the voltage sensor being greater than a predetermined voltage, to decrease the current reference to decrease the driving current of the light emitting diode.

Abstract: A washing machine including a motor regenerative braking configuration uses a buck power converter capable of reducing a direct current (DC) voltage, in association with charging an energy storage device when a voltage of a DC link capacitor becomes greater than or equal to a certain voltage. The washing machine uses the buck power converter in association with discharging the energy storage device and charging the DC link capacitor when the voltage of the DC link capacitor decreases. The washing machine may utilize regenerative braking energy by reducing or increasing a voltage amount provided from the energy storage device to a load by using a power conversion device.
