Abstract

Electronic cascaded systems are complex and extensively systems integrated with different converters. In general, there are two kinds of loads in these systems, constant power loads and constant voltage loads. The potential instability effected by constant power loads is analyzed with the power system of electric vehicle (EV) by impedance ratio criterion. The stability qualifications are given in this paper. Furthermore, a nonlinear control method is described to stable the systems with complex loads. The control effects are proved by simulations
