Dear wassay, hope that you have the answer of the question
29 May 2010 Buck/Boost Converter A DC DC Converter capable of buck/ Boost input voltage Author: Hadeed Sher

there are several books on this topic. generally this circuit is not used for BUCK/BOOST operation. designers use regular topologies of buck and boost for these specific tasks. The answer to this question is very well discussed in the book i mentioned above.

29 May 2010 Buck/Boost Converter A DC DC Converter capable of buck/ Boost input voltage Author: Hadeed Sher

well if you need a positive voltage then add an other BUCK/BOOST circuit with 52% duty cycle (Since at 50 % due to losses in circuit elements output will be slightly less then input).
Secondly the circuit elements needs redesigning if you disturb the input voltages to a very large extent. Theoretically it must give us infinite output voltage at 100 % duty cycle but it never happens because of the fact that practically there are always losses in circuit elements
