| Abstract |
An AC-based low-voltage distribution network can in some cases be replaced with a low-voltage direct current
(LVDC) network. With a higher DC voltage, the transmission capacity increases compared with the AC system with the same cable cross-sectional area. The DC link feeds an inverter that
converts the DC voltage to a 230 V single-phase or 400 V threephase
AC voltage. Because the three-phase voltage is not necessarily needed in most residential applications, this paper
presents two single-phase inverter topologies. Inverter modulation and its suitability for this kind of an application is
discussed. The inverter efficiency and its requirements are also discussed in brief, yet more precise analyses are left for future studies. The conclusion is that a half-bridge topology is not suitable for this application, and therefore, a full-bridge inverter should be used instead. |
