Abstract: This paper focuses on developing a novel method for the design of discrete buck booster converter with single phase power consumption. In this method, it uses converters based on high frequency frequency bridge-less interlaced width rectifiers. The merit of this method is that by incorporating interleaved boost converters intocomplete bridge diode rectifiers, switching and conduction losses can be significantly reduced. Here, we analyze the whole bridge in detail with the discrete buck-booster converter voltage coefficient. Voltage coefficient correction helps increase the voltage gain in the circuit. We use an optimized phase shift modulation strategy on a complete bridge discrete buck boost converter for improved performance and increase overall efficiency. Transformers with low ratios and low voltage MOSFETs and diodes can be implemented to improve efficiency. Based ton a variety of interlaced booster converters, including traditional booster converters and high step-up booster converters with voltage multipliers. From the point of view of conversion efficiency, the discrete buck-boost t(IBB) converter is ta good approach. Unfortunately, the fly-back converter tis ta typical IBB converter, but the efficiency is still very low due to the high voltage pressure on the components and rectangles. In this paper we give an input DC supply of 12V and an output voltage of 140V. The output prototype was designed to validate the effectiveness of the proposed IBB converters and its control strategies.
