摘要:
The purpose of the present invention is to minimize ozone production while increasing the production of an active species. The plasma generating device (100) comprises: a pair of electrodes (21, 22) in which dielectric films (21a, 21b) are disposed on at least one opposing face; voltage application means (4) for applying a pulse voltage across the electrodes (21, 22) to bring about a plasma discharger; and fluid circulation holes (21b, 22b) that are disposed in locations corresponding to the electrodes (21, 22), respectively, and that are configured to pass entirely therethrough. The plasma generating device is also configured such that a fluid passing through the fluid circulation holes (21b, 22b) comes into contact with the plasma, generating ions or radicals, wherein the voltage applying means (4) varies the peak value and/or the pulse width of the pulse voltage applied across the electrodes (21, 22).

摘要:
An apparatus and method to detect failure of an electrolytic capacitor that smoothes a DC voltage in an inverter circuit. The apparatus detects failure of a smoothing electrolytic capacitor in a motor drive inverter circuit that rectifies and smoothes an AC voltage through a rectifier and the smoothing electrolytic capacitor and converts a rectified and smoothed DC voltage into a 3-phase voltage to drive a motor. The apparatus includes a voltage meter, a current sensing unit, and a controller. The voltage meter measures a DC voltage of an inverter when the motor is not in operation. The current sensing unit measures a phase current of the motor when the motor is not in operation. The controller estimates an ESR value of the smoothing electrolytic capacitor from the DC voltage of the inverter and the motor phase current to detect failure of the smoothing electrolytic capacitor.

A method of controlling a washing machine and a motor determines whether a BLDC motor is in a normal state in software without hardware and a user is notified of an abnormal state of the BLDC motor if the BLDC motor is in an abnormal state, thereby ensuring safety. When the motor is rotated, the state of the motor is determined by applying harmonics to a voltage that is applied to a motor and analyzing an output frequency characteristic. When the motor is stopped, the state of the motor is determined by estimating the temperature of the motor.

A fault detection device includes an interface electrically connected to an electrical instrument to transfer commercial power to the electrical instrument, transmit a command for driving one of a plurality of loads included in the electrical instrument to the electrical instrument, and detect current flowing in one of the plurality of loads of the electrical instrument; and a terminal configured to receive a current signal corresponding to the current flowing in one of the plurality of loads from the interface, determine whether the one load has a fault on the basis of the received current signal and display whether the load has a fault. A faulty load is determined by detecting current of only a load suspected to have a fault when a fault is generated in the electrical instrument so as to improve fault detection accuracy.

In wireless Internet, a resource reservation path is established between a CH and a MH through an initial BS located in an initial cell where the MH is currently located. Pseudo reservation paths (PRPs) are established between the initial BS and its neighboring BSs, one PRP being established between the current BS and each of the neighboring BSs. Once the MH moves into one of the neighboring cells of the initial cell, a PRP established for a neighbor BS is activated. The activated PRP is concatenated with the established resource reservation path through the initial BS and the neighbor BS, thereby establishing an optimized resource reservation path.
