A power driving system for an electric vehicle with a motor includes plural battery boxes, a first DC bus, a second DC bus and a power converter. The first DC bus is electrically connected with the battery boxes for selectively receiving electric energy fr...

In order to provide a motor driving circuit in which a portion corresponding to a failed phase can be separated while miniaturization and lower costs are achieved, a motor driving circuit for driving a motor includes: a second driver circuit for driving a ...

An ECU (40) sets target value of a system voltage based on an electric power loss of a motor generator (MG1, MG2) and an inverter (20, 30) and controls a voltage boost converter (10). The ECU (40) calculates the target value of the system voltage using a f...
