Abstract

This paper presents the circuit modeling and control methods of PWM DC/DC converter with isolated dual outputs. The dual output converter consists of a transformer with a single secondary winding and two switches. The proposed control algorithm is that required inductor current according to the loads is feed-forwarded to the PI current controller. The proposed control method has better response characteristics than conventional PI control method at load change.
