Abstract

This paper proposes a transformerless dual half-bridge converter (TLDAHB). By eliminating the transformer and harnessing the possibility of using a low inductor value, it is possible to minimise the size of the converter. 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 are presented. Theoretical analysis consists of analysis of power transfer and design. In case of experimental research, particular attention was paid to power transfer and efficiency analysis. Near zero switching transient of voltage in the half-bridge topology results with high efficiency.
