Abstract
An object is to suppress an increase in current variation amount of a power storage device. A control device sets an allowable modulation factor, based on a circuit characteristic of a DC part that is on a power storage device side of an inverter, such that a current variation amount of the power storage device becomes equal to or smaller than an allowable current variation amount, and sets switching pattern commands of a plurality of switching elements, based on a set allowable modulation factor.
Claims6
A driving system, comprising:
- a motor;
- an inverter configured to drive the motor by switching of a plurality of switching elements;
- a power storage device connected with the inverter via a power line;
- a capacitor mounted to the power line;
- and
- a control device configured to add a dead time to switching pattern commands of the plurality of switching elements and perform switching control of the plurality of switching elements, wherein
- the control device sets an allowable modulation factor, based on a circuit characteristic of a DC part that is on a power storage device side of the inverter, such that a current variation amount of the power storage device becomes equal to or smaller than an allowable current variation amount, and sets the switching pattern commands of the plurality of switching elements, based on the set allowable modulation factor.
