Abstract :
A new method is proposed in order to obtain a fast, stable switched-mode power supply (SMPS): an AC feedback loop is added (besides the ordinary “DC” loop), which uses the voltage across the storage/filtering inductance(s) of the converter. With proper design, DC+AC feedback signal can have less than -π/2 phase shift and the SMPS can become unconditionally stable
