Abstract
A power converter includes one or more first conversion circuits, one or more second conversion circuits, and a controller. The first conversion circuit is configured to use a trench type transistor. The second conversion circuit is configured to use a planar type transistor. All the one or more first conversion circuits and all the one or more second conversion circuits are connected in parallel to each other or connected in series to each other. The controller stops all the one or more second conversion circuits and operates at least one of the one or more first conversion circuits while an output command value is lower than a predetermined output threshold value. The controller operates all the one or more first conversion circuits and operates at least one of the one or more second conversion circuits when the output command value exceeds the predetermined output threshold value.
