Abstract

In this paper, a mathematical model of electronic power transformer for distribution systems (DEPT) is established, and a nonlinear control scheme is proposed for high performance control of DEPT. The proposed control scheme is based on the state feedback exact linearization technique developed based on differential geometry theory. With this control scheme, the dynamic responses of the system become very fast. The system is tested for dc-link reference voltage, load and input voltages variations respectively. The validity of the proposed model and control strategy is demonstrated by simulation results.
