Experimental Verification of DC Bus Voltage Stability for Household Distributed Power System With Micro EV Battery

We have already clarified in our previous research that when multiple converters are connected to the DC bus the autonomously balanced charging can be performed without the current balance control. On the other hand, it can be assumed that other equipment connected to DC bus suddenly uses electricity. Therefore, when charging the battery from the DC bus, it is important to clarify the operation of the DC bus when power is supplied to another loads. In this paper, the stability of the DC bus voltage when electric power is supplied from the DC bus to other equipment while charging autonomously without the balance control has been studied.
