Unformatted text preview: L in series with a stray resistance r L . The duty cycle is defined as D , which represents the fraction of operating cycle time for which S 1 is gated; while (1 − D ) represents the fraction of time for which S 2 is gated. Identify the valid configurations, frame the configuration state equations, and hence the averaged state equations for the setup. Assume that the switches and diodes are ideal. ...(15) 3. Obtain a suitable incremental averaged model for the converter in Fig. P2 that can be suitably used for linear control. ...(5) 4. In the digital domain, a second order converter transfer function is found to have marginally stable complex conjugate poles in open loop, with no zeros. Show that if the converter control loop is closed through a positive feedback path, then it is possible to make the poles perfectly stable ...(10) EEE G545/10/Compre + V S S D D 1 1 2 2 1 + V 2 P2...
