A step-up/down single-stage ZVS inverter
IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society, 2015In many applications such as power converters for fuel cells or distributed generating (DG) systems there is a need to increase the DC voltage before being inverted to AC grid or load with a higher voltage. The standard approach is to use a DC-DC converter to boost the input voltage followed by a buck inverter to converter the increased DC voltage into
