A power electronic transformer (PET) with a cycloconverter on the grid side is being proposed in this paper for integrating several renewable energy sources to the grid. A single 1-phase multi-winding high frequency transformer connects multiple wind energy conversion systems and solar photovoltaic arrays to the cycloconverters using separate H-bridge PWM converters. The current is smooth and continuous...
This paper presents a novel DC-AC inverter based on a high frequency power electronic transformer. It makes use of an adapted push-pull converter on the primary side of the transformer to apply a high frequency alternating voltage. This keeps the transformer flux low and transformer size small, reducing the cost of materials but at the same time keeping the power density high. The secondary side is...
