Problem 66

A dc-dc converter is a device that takes as an input an unregulated dc voltage and provides a regulated dc voltage as its output. The output voltage may be lower (buck converter), higher (boost converter), or the same as the input voltage. Switching dc-dc converters have a semiconductor active switch (BJT or FET) that is closed periodically with a duty cycle d in a pulse width modulated (PWM) manner. For a boost converter, averaging techniques can be used to arrive at the following state equations (Van Dijk, 1995): L diL dt 1 duc Es C duC dt 1 diL uC R where L and C are, respectively, the values of internal inductance and capacitance; iL is the current through the internal inductor; R is the resistive load connected to the converter; Es is the dc input voltage; and the capacitor voltage, uC, is the converters output. a. Write the converters equations in the form x_ Ax Bu y Cx assuming d is a constant. b. Using the A, B, and C matrices of Part a, obtain the converters transfer function UCs Ess :
