Bi-directional Inverter with DC-Bus Voltage Regulation and Power Compensation in DC-Micro Grid System

Snehal H. Bhandarkar | S. S. Hadpe

Abstract: The objective of this paper is to propose single phase bi-directional inverter which will do DC bus voltage regulation and power compensation for DC microgrid applications. Due to defects of the traditional AC grid power supply DC microgrid is an effective solution to integrate renewable energy sources which are DC power supply with DC load & this system would be more efficient. In DC microgrid system it will required bi-directional inverter to control power flow between AC and DC grid and to regulate the DC bus voltage up to certain range. This bi-directional inverter has to full fill rectification and real power injection by reducing harmonics level. Experimental results obtained from 400VA single phase Bi-directional inverter.
