Phase Shaping Method for Negative Input Admittance of Buck Converter Based on Sliding Mode Disturbance Observer

Phase Shaping Method for Negative Input Admittance of Buck Converter Based on Sliding Mode Disturbance Observer

The power electronic converter that supplies power to the unmanned ship's servers can cause self-excited oscillation of the LC input filter under heavy load. To suppress voltage oscillation, an input impedance shaping method based on a sliding mode disturbance observer is presented. The self-ex...
