Abstract :
In this paper a new single switch Buck-Boost type dc-dc converter is introduced. This converter consists of flyback and forward transformers and only one switch in primary side and one diode in secondary side of transformers. Also this converter operates in both buck and boost modes. In this converter energy transfers to the output in both on and off switch states and controlled by PWM signal. Therefore implementation of control circuits is easy and cheap. Since this converter operates over a wide input voltage range, this converter can be employed as a power factor correction. Theoretical analysis is presented and computer simulation results verify the converter analysis.
