A voltage doubling circuit that increases input voltage to higher output voltage connected to a variable frequency drive. The voltage doubling circuit can include a power input that receives the input voltage from a power source and a first capacitor bank and a second capacitor bank connected with the power input. A current-limiting surge suppressor is positioned between the power input and the first capacitor bank and the second capacitor bank. The current-limiting surge suppressor includes a first current-limiting path and a second bypass path. A drain, when operable, dissipates the charge of the first capacitor bank and the second capacitor bank. A variable frequency drive (VFD) is operable in response to the higher voltage output from the first capacitor bank and the second capacitor bank.

A household appliance contains a DC power supply configured to provide a DC supply voltage between a first DC supply line and a second DC supply line from an external DC supply, which is external to the household appliance. Furthermore, the appliance contains an electrical component which is configured to be operated by the DC supply voltage. The appliance further contains at least one DC switching circuit having a semiconductor-based switching element which is configured to galvanically interrupt the first DC supply line or the second DC supply line in reaction to a control signal.

A home appliance having a motor includes: an inverter unit; and an inverter control unit for controlling a switching operation of the inverter unit, wherein the inverter control unit generates a braking command for braking the motor, on the basis of an operating mode of the home appliance, and controls the inverter unit to stop the motor when a preset braking time elapses after the braking command is generated, and to execute a first braking mode in which the rotational speed of the motor is reduced in a state where no current flows in the inverter control unit, and then to execute at least one of a second braking mode and a third braking mode in which the rotational speed of the motor is reduced in a state where a current flows in the inverter control unit.

A heater arrangement for a multi-compartment appliance comprises a first heater, a second heater, and a relay. The first heater is disposed within a first airflow path for a first dryer compartment. The second heater is disposed within a second airflow path for a second dryer compartment. The relay interconnects, via an electrical harness, the first and second heaters. The relay, responsive to a demand for heat to the first dryer compartment and the first heater having a temperature being less than a target temperature, diverts power to the first heater.

A washing apparatus is provided. The washing apparatus includes a main body having a door, a spin basket disposed inside the main body and rotating about a rotary shaft, a motor providing power to the rotary shaft, a spring clutch including a first core rotating in conjunction with the motor and a second core rotating in conjunction with the rotation shaft, and selectively transmitting power of the motor to the spin basket, a processor, and a sensor that measures revolutions per minute (RPM) of the spring clutch, and when the driving of the motor based on an input signal is completed, the processor controls to stop the driving of the motor, and after stopping the driving of the motor, controls the motor to be re-driven for a preset driving time based on a measurement value of the sensor.

The present disclosure relates to a laundry treatment machine. A laundry treatment machine according to an embodiment of the present disclosure includes: an inverter converting a direct current (DC) voltage from a converter into an alternating current (AC) voltage based on a switching operation and outputting the converted AC voltage to a circulation pump motor; and a controller to control a speed of the circulation pump motor to be increased before a time point at which a speed of a washing tub motor increases.
