Webresponse of the duty-cycle-to-output-voltage transfer function. The inverting buck-boost is a popular non-isolated, inverting power stage topology. Power supply designers choose the inverting buck-boost power stage because the output voltage is inverted from the input voltage, and the output voltage can be either higher or lower than the input ... WebOf course we take the boost set of parameters, plug that into the simple model, and compute control to output transfer function, which for the simple model is actually very simple. The control-to-output transfer function is simply going to be equal to f2 times the parallel combination of r2, c, and R, with the scale factor of 1 over Rf in front.
