  • Publication number: 20210281186
    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.

  • Patent number: 9548657
    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.
