In this chapter, analysis and comparison between AC and DC microgrid in residential buildings have been done based on appliances, converters and their power losses in both systems. The layouts for LVDC distribution network have been discussed. Both unipolar and bipolar layouts of LVDC system have been discussed. Two microgrid system configurations have been discussed: AC residential building [i.e. AC distribution system (ACDS) with DC appliances] and DC residential building (i.e. distribution network with DC appliances).
