We have proposed the sensorless model control based on the static model equation of the dc-dc converter that is able to change the bias value corresponding to changes of the load current, the input voltage and output voltage. The sensorless model control can regulate the output voltage. On the other hand, the transient response of output voltage is not improved. Therefore, an improvement of the transient...
The purpose of this paper is to discuss a current prediction algorithm for sensorless model control dc-dc converter. In the proposed method, the sensing resistor for the current detection is eliminated by predicting the output current. The output current is predicted from the equation of the relationship between the output and input voltage in the static state using the duty ratio and the output voltage...
The purpose of this paper is to present a novel reference modification dc-dc converter using the reactor current sensing method and to compared its transient characteristics with the conventional output current sensing method. The proposed method uses the reactor current sensing method with the R-C filter in order to exclude the sensing resistor for the output current sensing method. Moreover, transient...
