TRANSFORMERLESS HIGH BOOST DC-AC PULSE INVERTER

摘要

The invention object relates to the electrical engineering and power electronic field. Controllability, power density, regulation range are very essential in power electronic converters. The invention (fig.2) proposes enhancement of those characteristics by means of single stage energy conversion, high step-up transformerless topology and two inverters (11, 12) of CUK-type. Transformereless high boost DC-AC inverter could be used in different kind of power generation systems. The most promising are applications with photovoltaic solar systems due to voltage balancing capability and other renewable and alternative energy generation sources.
