   CO2 Footprint of DC Solid State Transformer for Linear PV Power Plant
By Pierre LE METAYER, Adriana CAMPOS, Piotr DWORAKOWSKI [View]
[Download]

Abstract: This paper presents a comparison of the carbon footprint of a DC SST designed for a linear PV application with MVDC collection network, and its counterpart for a traditional MVAC architecture. A method is proposed, allowing to calculate the CO2 footprint of the DC SST accounting for the manufacturing emissions of the PV modules. It is found that the energy efficiency of the conversion chain tends to be less and less significant to the overall carbon footprint as the energy mix shifts towards renewable energy sources. The manufacturing emissions of the conversion chain are thus to be reduced in the future. For PV power plants this can be achieved thanks to MVDC collection network.

   Three-Phase PFC Rectifier with only two AC-side Transistors P2S6
By Simon PETER, Karl Stephan STILLE, Jan Boris LOESENBECK [View]
[Download]

Abstract: A novel three-phase AC/DC converter topology consisting of an input side pulse inverter and an output side rectifier is presented. The pulse inverter produces an electrically isolated three-phase voltage using only two active switches. This voltage is rectified by a three-phase boost converter. A control scheme with internal hysteresis control is designed for the rectifier, which allows fast current adjustment and ensures PFC operation. The topology is simulated and verified in practice.
