摘要： A motor driving device that drives a motor with an alternating-current power converted from a direct-current power supply, includes an inverter that receives a pulse-width modulation signal and supplies the alternating-current power to the motor, and an inverter control unit that generates the pulse-width modulation signal and supplies the pulse-width modulation signal to the inverter. The inverter control unit reduces the number of pulses of the pulse-width modulation signal generated during a first period within one period of a mechanical angle of the motor to be lower than the number of pulses of the pulse-width modulation signal generated during a second period within the one period of the mechanical angle of the motor. The first period is a period during which a load torque is lower than a load torque during the second period.

摘要： An air conditioner in which a mixed refrigerant that includes at least 1,2-difluoroethylene is used, wherein increased efficiency is achieved. The motor rotation speed of a compressor (100) can be changed in accordance with the air conditioning load, and therefore it is possible to achieve high annual energy consumption efficiency (annual performance factor). Furthermore, no electrolytic capacitor is required on the output side of a rectification circuit (21), and therefore increased size and cost of the circuit can be suppressed.

摘要： According to the present invention, when a power supply power factor changes in a lagging direction, control units (43,47,52,62)perform a first control for controlling the power supply power factor or a power supply harmonic under a harmonic current such that an input power factor of at least one of a plurality of connection devices (41, 42) changes in a leading direction compared to the power supply power factor. In addition, when the power supply power factor changes in the leading direction, the control units (43,47,52,62)perform a second control for controlling the power supply power factor or the power supply harmonic such that an input power factor of at least one of the plurality of connection devices (41, 42) changes in the lagging direction.

摘要： A method, device, and system for controlling power delivered to a power-consuming device. The device can harvest power from a conductor carrying a high voltage using a power harvesting device. The device can include a power storage device to power a hardware processor and a communication component when there is no voltage flowing through the conductor. The device can determine when a control event is to occur. At such time, the device terminates control power delivered to the power-consuming device and continues to withhold the control power until the control event expires. When the control event has ended, the device allows control power to flow to the power-consuming device. The device uses a timer and the communication component to send and receives signals associated with a control event to a user. The device can also operate in a limited mode to conserve power when the device is not in use.

The apparatus comprises an indoor unit circuit and an outdoor unit circuit, wherein the indoor unit circuit comprises an indoor unit communication module, an indoor unit communication module output signal acquisition module and an air-conditioning circuit identification module; the outdoor unit circuit comprises an outdoor unit communication interface; the indoor unit communication module is in communication connection with the outdoor unit communication interface; the indoor unit communication module output signal acquisition module is connected to the indoor unit communication module; and the air-conditioning circuit identification module is connected to the indoor unit communication module output signal acquisition module. The method comprises: when an air-conditioning circuit is energized but is not started, acquiring an output signal of an indoor unit communication module; and according to the output signal, identifying the air-conditioning circuit to be a low power-consumption standby circuit or a non-low power-consumption standby circuit. After an air conditioner including the apparatus is energized, whether an air-conditioning circuit is a low power-consumption standby circuit is determined, thereby preventing an indoor unit circuit from incorrectly controlling the entering of an outdoor unit circuit into a low power-consumption mode or a non-low power-consumption mode, and avoiding unnecessary control mistakes and energy waste.
