Abstract

The method of using output-current-feedforward (OCFF) control to realize zero output impedance is widely applied in Buck converter. However, it is found that the converter may have stability problems with this method. The OCFF controller's transfer functions of basic DC/DC converters are calculated when different current (inductor current, load current) feedforward control is used in this paper There is a negative feedback loop existing in this model as OCFF control is applied and this loop may cause instability. The system stability of Buck converter with different current feedforward control is analyzed. The theories are verified by simulation and experiment results of Buck converter.
