Claims

[Scope of utility model registration request]

In an AC electric car driven by two or more separately excited motors connected in parallel (including two parallel connections of multiple separately excited motors), the current imbalance between the two parallel motors can be corrected by using an accelerator with a center point. AC electric vehicle main circuit device characterized by applying the current balancing effect of .
