Abstract

The purpose of this study is the fast response control of the output voltage of DC-DC converters to the load current change. A method to control the output voltage fast and to reject the influences of the load change is proposed. Constant frequency carrier waves are used to keep switching frequency constant in the steady state. The amplitude of the triangular carrier wave is proportional to the power supply voltage to decrease steady-state error occurred by the distortion of the supply voltage. This method uses the PD control to improve the stability of the system
