Abstract
A drive circuit for a motor/generator, having a first rotating electrical machine which is mainly used as a motor and a second rotating electrical machine which is mainly used as a generator, is characterized in that a booster circuit is disposed at a position where the current for rotating the first rotating electrical motor cancels out with the current generated by the second rotating electrical machine. In this manner, the booster circuit comprising small capacity elements can be used in the drive circuit for the motor/generator.
