| Abstract |
This paper introduces a unidirectional MVDC-HVDC converter for `all DC' connected offshore windfarms. This converter combines the low power losses of thyristor based converters and the controlabilities of voltage source converters, together with low power electronics component count. A highstep-up ratio is achieved by an input parallel output series configuration. The use of medium frequencyis discussed and inductance design conditions are given. A control scheme is proposed and validated bysimulations. The converter high efficiency is also observed. The presented analysis shows a potentialfeasibility and benefits of this novel unidirectional thyristor-based DC-DC converter. |
