Current-fed full-bridge DC-DC converter with nonlinear control scheme
Résumé
This paper presents a control algorithm for dealing with the constraints of energy power source and a current-fed full-bridge converter. The advantages of this control scheme include transient and steady-state responses and robustness. The prototype of 26 V/100 V 250 W and its controller were implemented. A dSPACE DS1104 was used to implement the outer control loop by using flatness system's properties. An analog control card was employed as an inner control loop by using hysteresis-based PWM. The validation of the proposed control was demonstrated through experiment results.
