摘要： An environmental control equipment control apparatus controls an environment of a target space using a plurality of environmental control equipment. The control apparatus includes a receiver and an electronic controller. The receiver may receive state information relating to states of a plurality of subject persons. In this case, the electronic controller controls a plurality of kinds of environmental control equipment such that the state information of the plurality of subject persons received by the state information receiver satisfies a predetermined target state condition. The receiver may receive a second environmental stimulus given to a subject person other than a first environmental stimulus caused by control of the environmental control equipment. In this case, the electronic controller controls the environmental control equipment such that an influence of the second environmental stimulus received by the environmental stimulus receiver on the subject person is cancelled or reduced.

摘要： An inverter circuit (120) is configured so as to perform synchronous rectification by six switching elements (130). The switching element (130) is formed of an unipolar device (SiC MOSFET in this case) using a wideband gap semiconductor. The inverter circuit (120) uses the body diode (131) of SiC MOSFET (130) as a freewheeling diode during synchronous rectification.

摘要： A DC link has first and second power supply lines. A first rectifying circuit has a plurality of input terminals that input an AC voltage and a pair of output terminals connected to the DC link. An inverter converts a voltage applied to the DC link into another AC voltage. A boost chopper has a capacitor at an output stage. A switch switches discharge and non-discharge from the capacitor to the DC link. In the boost chopper, charge into the capacitor is performed at least at a first period. The first period is a part of a period during which a discharge duty as a time ratio of continuity of the switch is larger than 0.

摘要： An operation area of a motor is increased without increasing the capacity of a switching element. A current limiter which limits a current flowing in switching elements to prevent the current from exceeding a predetermined current limit value is provided. A current limit value controller which decreases the current limit value if a loss generated in the switching elements increases at a same current value, and increases the current limit value if the loss decreases at a same current value, is provided.

摘要： A setting facilitation apparatus (1400) includes a keyword input reception section (1410), a control command selection section (1420), and a specific control registration section (1430) and is used to facilitate setting of specific control in a control system (1001) that controls a control device through sound inputs. The keyword input reception section (1410) receives an input of information corresponding to a keyword. The control command selection section (1420) displays a certain control command to the control device (1010, 1020) on an edit screen (G) and receives selection of the control command. The specific control registration section (1430) registers a keyword (K) input by the keyword input reception section (1410) and the control command selected by the control command selection section (1420) to a specific control (DB 1104T) while associating the keyword and the control command with each other.

摘要： An air conditioning control device includes a control unit, a skin temperature measurement unit, an information acquisition unit, and a determination unit. The control unit controls an air conditioner that performs air conditioning of a room where a user is present. The skin temperature measurement unit measures a skin temperature of the user. The information acquisition unit acquires thermal sensation information of the user regarding the space where the user is present. The determination unit determines a comfortable skin temperature range in which the user feels comfortable, based on a skin temperature of the user obtained at the time of acquiring of the thermal sensation information. The control unit controls the air conditioner based on the comfortable skin temperature range determined by the determination unit.

摘要： In a power converter, vibration and noise of a motor due to pulsation of a direct current link voltage are reduced. An inverter circuit is provided, which is configured to convert a direct current link voltage having a pulsating component to an alternating current to output the alternating current to a permanent magnet synchronous motor. A controller is provided, which is configured to control the inverter circuit by vector control and which, in a control state in which fundamental voltage vectors do not include a zero vector (voltage vector for which a motor terminal voltage is zero), performs such control that the phase of a resultant voltage vector of a d-axis voltage vector and a q-axis voltage vector of the permanent magnet synchronous motor varies depending on pulsation.
