Claims

[Scope of utility model registration request]

In a chopper control device for an electric vehicle, which connects a chopper main circuit in series to a DC compound-wound motor and controls the operation of the motor by controlling the conductivity of the chopper main circuit, the chopper main circuit changes from a high conductivity control state to a low conductivity. 1. A chopper control device for an electric vehicle, characterized in that a control command includes means for suppressing a rapid decrease in conductivity.
