摘要： According to one embodiment, when an effective value of an input current flowing into a booster circuit rises to a value greater than or equal to a second set value, boosting of the booster circuit is started and, after the start, when the effective value lowers to a value lower than a first set value lower than the second set value, boosting of the booster circuit is stopped. Then, if the three-phase AC source is in an unbalanced state, the first set value is set to a value lower than usual.

摘要： The present invention is an electric motor drive 100 which drives an electric motor 4 by using AC power converted from a DC power source I, said electric motor drive device 100 being provided with: an inverter 5 that receives a pulse width modulation signal and supplies AC power to the electric motor 4; and an inverter control unit 8 that generates a pulse width modulation signal and supplies said signal to the inverter 5. The inverter control unit 8 reduces the pulse number of the pulse width modulatuion signal generated in a first interval of one cycle of a mechanical angle of the electric motor 4 to a level lower than the pulse width modulation signal generated in a second interval of one cycle of the mechanical angle of the electric motor 4. The first interval is an interval which has a load torque that is lower than the load torque of the second interval.

摘要： An HVAC unit includes a transformer and a system controller. The transformer is configured to receive power from a first and a second phase of a three-phase power source and to produce a first reduced-voltage waveform therefrom. The system controller is adapted to sample the reduced voltage waveform to determine a figure of merit of the three-phase power source. The controller is further configured to operate the HVAC unit in response to the figure of merit.

摘要： A control device, such as a smart thermostat, employs solid state relays as switches to activate and deactivate systems controlled by the device. Current flows through at least some of the solid state relays are monitored to determine the bulk heating produced in the solid state relays, and their associated circuitry and printed circuit board traces, and this determined amount of bulk heat is added to other determined amounts of bulk heat and is used to compensate the reading provided by temperature sensors within the control device which have been affected by the bulk heat. Further, by measuring the current flow through the power buses to one or more of the solid state relays of the control device, potentially damaging over current conditions can be distinguished from permissible transient over-current conditions and the control device can deactivate any solid state relays which would be damaged while allowing solid state relays which are experiencing allowable transients to remain operating. In the case of a severe over current condition, a current monitoring device can issue a fault signal, triggering an interrupt condition which will cause a processor in the controller to shut down the affected solid state relays very quickly.

摘要： An inverter device includes a plurality of switching circuits (5) in which first switching elements (8) including Si semiconductors and second switching element (9) including WBG semiconductors having ON resistance smaller than that of the first switching elements (8) and having switching speed higher than that of the first switching elements (8) are connected in parallel. The inverter device includes a converting circuit (4) that converts a direct-current voltage into a desired alternating-current voltage and a driving unit (16) that generates a plurality of driving signals for respectively turning on and off the switching circuits (5). The inverter device includes, for each of the switching circuits (5), a gate circuit (17) that, based on the driving signals, turns on the second switching element (9) later than the first switching element (8) and turns off the first switching element (8) later than the second switching element (9).
