| Abstract |
This paper provides theoretical formulations to achieve load invariance of a switched-mode converter and investigates the load sensitivity of a peak-current-mode controlled (PCMC) buck converter with output current feedforward (OCF). Theoretically, a converter having zero output impedance would provide full load invariance. In practice, a converter can be made highly insensitive to load interactions, if unity-gain feedforward of output current is used together with peak-current-mode control. However, non-idealities of the practical implementation can deteriorate the obtainable level of insensitivity. Experimental frequency-domain measurements are used to prove the theoretical predictions. |
