Abstract

The electrical motor drives and power electronic converters of More Electric Vehicles usually behave as constant power loads (CPLs), and cause negative impedance instability. This paper introduced R parallel damping filters to stabilize the CPLs systems, and derived large signal stability criteria depending on Brayton-Moser’s mixed potential theory. The simple criteria utilize the maximum negative impedance of the CPLs to give quantitative constraints on the filter parameters. Comparisons indicate the stability criterion for the CPLs with a LC filter can be regarded as a special case of the proposed criteria. The experimental results confirm the validity of the large signal stability method.
