How does Circulating Current Arises in Dual Converter?
The circulating current arises because of the difference in the firing angles (also known as phase shift) between the rectifier and the inverter. When the firing angle of the inverter is different from that of the rectifier, it causes a phase difference between the rectifier output voltage and the inverter output voltage. As a result, the DC link voltage fluctuates periodically.
The DC link reactor, being an inductive component, opposes changes in current. When the DC link voltage fluctuates, it induces a circulating current through the reactor to stabilize the voltage. This circulating current flows between the rectifier and the inverter through the DC link reactor, compensating for the phase difference and stabilizing the DC link voltage.
How to Calculate Circulating Current across Reactor under Dual Converter?
Circulating Current across Reactor under Dual Converter calculator uses Circulating Current = (1/(Angular Frequency*Circulating Current Reactor))*int(Instantaneous voltage Across Reactor,x,(Delay Angle of First Converter+(pi/6)),(Angular Frequency*Time)) to calculate the Circulating Current, The Circulating Current across Reactor under Dual Converter refers to the current that flows through the reactor due to the phase difference between the firing angles of the rectifier and the inverter in the dual converter system. Circulating Current is denoted by ic symbol.
