Question: The input voltage V g is dc and positive with the polarity shown. Specify how to implement the switches using a minimal number of diodes

The input voltage V _g is dc and positive with the polarity shown. Specify how to implement the switches using a minimal number of diodes and transistors, such that the converter operates over the entire range of duty cycles 0≤ D ≤ I. The switch states should vary as shown in Fig. You may assume that the inductor current ripples and capacitor voltage Tipples am small. For each problem. do the following:

(a) Realize the switches using SPST ideal switches. and explicitly define the voltage and current of each switch.

(b)Express the on-state current and off-state volt age of each SPST switch in terms of the converter inductor currents, capacitor, voltage, and/or inuput source voltage.

(d) Determine the polarities of the switch on-stale currents and off-state voltages. Do the polarities vary with duty cycle?
