<P>PROBLEM TO BE SOLVED: To provide a power converter which is low loss, capable of controlling the power supplied from power sources into an arbitrary value, and realizes power shifting among power sources at high efficiency. <P>SOLUTION: The power converter 30, which generates a drive voltage of a motor 20 from voltage sources 10a and 10b, includes a motor current command value generating means; a means of acquiring motor voltage command value; a means of generating power source power command value and output voltage command value; and an output pulse generating means 47. The output voltage command value generating means generates an output voltage command value, based on a second output voltage vector and a first output voltage vector, when a combined vector of a first output voltage command vector, which corresponds to a voltage source to be charged and satisfies the power source power command value, and a second output voltage command vector, corresponding to a voltage source to be discharged, coincides with the motor voltage command vector corresponding to the motor voltage command value; while a motor current command vector, corresponding to the motor current command value, is positioned within an included angle formed between the inverse vector of the first output voltage command vector and the second output voltage command vector. <P>COPYRIGHT: (C)2008,JPO&INPIT |
