Abstract: A power storage system includes: a battery including a first power storage, a second power storage, and a first switch unit; a three-phase motor in which coils of three phases are connected at a neutral point, the three-phase motor being driven by electric power supplied from the battery; an inverter connected on an electric power transmission path between the battery and the three-phase motor; a DC power supply circuit connected to a first connection portion positioned on an electric power transmission path between the inverter and the battery; a capacitor provided on the electric power transmission path between the battery and the three-phase motor; and a branch circuit that branches off from the DC power supply circuit on a positive electrode side and is connected to a coil of any one phase among the coils of three phases. The first switch unit includes a semiconductor switch.

Abstract: A conversion apparatus includes: a conversion module having plural phases, each including a converter and a sensor, in which the plural phases are electrically connected in parallel, and a controller. The controller includes a first unit for determining a basic duty ratio common to all of the plural phases, so that an input or an output of the conversion module becomes equal to a target voltage or a target current, a second unit for determining a correction duty ratio and correcting the basic duty ratio for each of the plural converters, and a generator for generating the control signal based on the basic duty ratio and the correction duty ratio. The second unit determines the correction duty ratio based on a difference between plural phase currents respectively flowing in the plural converters. The basic duty ratio is equal to or greater than an absolute value of the correction duty ratio.

Abstract: In electric equipment, a switching substrate is provided along winding axes of winding parts. A part of the switching substrate is overlapped with a reactor, as viewed in a direction perpendicular to a virtual plane including the winding axes. Further, an electric current sensor is shifted from the reactor in a direction of winding axes, and a sensor substrate is provided in parallel to the virtual plane.

Abstract: When a control device simultaneously drives first and second direct-current power converter circuits, the control device can arbitrarily control a first voltage and a second voltage, and a load voltage by changing at least one of first and second duties. The control device generates a loop current, which discharges a first power source and charges a second power source, or a loop current, which charges the first power source and discharges the second power source, in a loop circuit where a first reactor and a second reactor are connected in series.
