The dc voltage transfer function and the efficiency of the converter are derived from the dc model. Small-signal open-loop transfer functions are derived from the small-signal model. The derivation of the transfer function for an integral-lead controller with the loading effect of the voltage ...
Notice that the current slope is a function of the input voltage (Equation (1)), and that a shift in gain will occur from that changing slope. The effect is similar to that of voltage feedforward in the VMC converter. The current feedback path has a transfer function in CCM, but not...
For derivation of the converter model, the steady state analysis is given in details and the required equations are formulated. The transfer function expression is obtained using the averaging model of the converter and then, the description and comparisons are introduced to reveal the features and ...
