  • Publication number: 20240388221
    Abstract: A current suppression control unit calculates a correction amount of a reference voltage command value for operating a power converter as a voltage source, and sets an amplitude value of a voltage command value by reflecting the correction amount in an amplitude value of the reference voltage command value. The correction amount is set to make the amplitude value of the voltage command value smaller than the amplitude value of the reference voltage command value, in response to a decrease in an AC voltage at an interconnection point.

  • Patent number: 12117250
    Abstract: A heat exchanger (100) includes a flow path layer (10) in which a first flow path (11) extending in a first direction and a second flow path (12) extending in a second direction are disposed in the same layer. In each of the first flow path and the second flow path, a flow path cross-sectional area is reduced and expanded along an extending direction of the flow path. The first flow path and the second flow path intersect each other in the same layer in first portions (23, 33) of which the flow path cross-sectional area is reduced, due to displacement of the first portions (23, 33) in a third direction.

  • Publication number: 20240297597
    Abstract: A current suppression control unit calculates correction terms of reference voltage command values for operating a power converter as a voltage source. The correction terms are calculated to compensate for respective current deviations of output currents transformed on two axes, with respect to current command values on a two-axis rotating coordinate system for suppressing an output current of the power converter to less than or equal to a control upper limit value. A proportional control unit has proportional elements to reflect the current deviations in the correction terms within the same axes of the two axes. A decoupling control unit has integral elements to reflect the current deviations in the correction terms between the different two axes.
