Abstract
An electric system including a first converter and a second converter connected in parallel executes a program including a step of controlling a value of a voltage of a section between the first converter and the second converter to be higher by a predetermined value than either voltage value V(1) or voltage value V(2), whichever is higher, and a step of controlling the value of the voltage of the section between the first converter and the second converter to attain to the same voltage value as either voltage value V(1) or voltage value V(2), whichever is higher.
Claims12
A control device for an electric system, comprising:
- a first converter for varying a voltage;
- a second converter connected in parallel to said first converter for varying a voltage;
- a first power storage mechanism connected to said first converter for storing electric power;
- a second power storage mechanism connected to said second converter for storing electric power;
- a first voltage sensor for detecting a voltage of said first power storage mechanism;
- a second voltage sensor for detecting a voltage of said second power storage mechanism;
- and
- a control unit for controlling said first converter and said second converter based on either the voltage of said first power storage mechanism or the voltage of said second power storage mechanism, whichever is higher, and a difference between the voltage of said first power storage mechanism and the voltage of said second power storage mechanism.
