Özet

© 2016 IEEE.The switching power supply is required the wide load range operation for the energy saving. In such a situation, the output voltage must be regulated. The model control is able to regulate the output voltage, because the bias value is varied depending on the static model equation. Thus, it is effective for switching power supply to implement the model control. The existing sensorless model cannot have a quick response. The purpose of this paper is to improve the transient response of the sensorless model control DC-DC converter by setting the parameter of the function that changes the operating point for a short time at the start of the transient state. It suppresses the undershoot of output voltage. The validity of the proposed method is confirmed by comparison with existing model control method and the proposed sensorless model method.
