ABSTRACT
This paper proposes a transformerless dual half-bridge converter (TLDAHB). It is possible to minimize the size of the converter due to elimination of the transformer and the possibility of using a low inductor value. A phase-shift pulse width modulation will result in a wide controlled voltage gain of the converter and operation as buck and boost. The theoretical topology analysis, simulation, and experimental results were presented. Theoretical analysis consists of analysis of power transfer and design. In case of experimental research par-ticular attention was paid for power transfer and efficiency analysis. Near zero switching transient of voltage in the half-bridge topology results with high efficiency.
