Document Type and Number:
Japanese Patent JP7086268
Kind Code:
B2
Abstract:
A drive device includes a first inverter and a second inverter configured to respectively drive two rotary electric machines. Carrier signals for controlling the first inverter and the second inverter are set to be in mutually opposite phases. For at least one connection line out of a connection line between the first inverter and one of the rotary electric machines and a connection line between the second inverter and another one of the rotary electric machines, a balance capacitor and a balance inductor are disposed between the at least one connection line and a ground potential such that an impedance to ground generated between the one of the rotary electric machines and the ground potential coincides with an impedance to ground generated between the other one of the rotary electric machines and the ground potential.
