Abstract: A linear compressor includes a cylinder, a piston, a linear motor configured to drive the piston, a current detection unit configured to sense a current in the linear motor, a relay configured to change an operation mode of the linear motor, and a control unit configured to set at least one parameter for determining a stroke of the piston according to the operation mode. The control unit is configured to: determine a first magnitude of a first current in the linear motor based on a state of the relay being in a first state, determine a second magnitude of a second current in the linear motor based on the relay being switched to a second state from the first state, compare the first magnitude to the second magnitude, and based on the comparison of the first magnitude to the second magnitude, determine whether the relay fails to operate.

Abstract: An appliance includes a driver to drive a load, the load requiring AC power or DC power. A power supply receives one of external AC power, back-up AC power and back-up DC power and outputs at least one of AC power or DC power to the load. An operation mode of the home appliance is one of normal operation when receiving external AC power, normal operation when receiving one of back-up AC power and back-up DC power during a power interruption, and a power save mode when receiving one of back-up AC power and back-up DC power during the power interruption. The power supplies a first power level when there is no power interruption, a second power level when there is power interruption and a third power level when there is power interruption and the power save mode is selected, where the second power level is between the first power level and the third power level. The power save mode is automatically selected when the second power level falls below a reference power level.
Abstract translation: 设备包括驱动负载的驱动器，负载需要交流电源或直流电源。 电源接收外部交流电源，备用交流电源和备用直流电源之一，并向负载输出至少一个交流电源或直流电源。 家用电器的操作模式是在接收到外部AC电力时正常操作之一，在接收到电源中断期间接收备用AC电力和备用DC电力之一时的正常操作以及当接收到后面的一个时的省电模式 在电源中断期间提供交流电源和备用直流电源。 当没有电源中断时，电源提供第一功率电平，当电源中断时具有第二功率电平，当电源中断时选择第三功率电平，并且选择省电模式，其中第二功率电平在第一功率电平之间 功率电平和第三功率电平。 当第二功率电平低于参考功率电平时，自动选择省电模式。
