Abstract

In a controller and a control method for a power converter of a vehicle, the power converter has a first operation mode and a second operation mode defining power supply modes of first and second DC power supplies with respect to a load. The first operation mode is an operation mode set when the first and second DC power supplies are electrically connected in series to an electric wire electrically connected to the load. The second operation mode is an operation mode set when the first and second DC power supplies are electrically connected in parallel to the electric wire. The controller includes an electronic control unit. The electronic control unit is configured to execute warm-up promotion control of a catalytic device. The electronic control unit is configured to set the operation mode of the power converter to the second operation mode when executing the warm-up promotion control.

Description

technical field [0001] The present invention relates to the technical field of controllers and control methods of power converters. Background technique [0002] As a power converter suitable for a vehicle including a plurality of direct current (DC) power sources, there has been provided a power converter which can switch between the electrical connection relationships between the plurality of DC power sources and loads (see No. 2012-070514 ( Japanese Patent Application Publication No. JP2012-070514A). As operation modes for defining these electrical connection relationships, JP2012-070514A discloses a serial mode in which a plurality of DC power sources and loads are electrically connected in series, and a parallel mode in which a plurality of DC power sources and loads are electrically connected in parallel. [0003] Furthermore, Japanese Patent Application Laid-Open No. 2000-295715 (JP2000-295715A) discloses a configuration including a mode in which two DC power sources...
