The Key Technology in the Parallel Control of Inverter

Abstract:

Flow equalization is one of the key technologies in the parallel control of inversion module. This paper presents the multi-inversion module parallel flow equalization system with TMS320LF2407A as the main control chip, which adopts the control strategy of “synchronous control of seizure and coincidence”, gains the data communication in the multi-module parallel connection and the multi-inversion module parallel flow equalization control with CAN controller embedded in TMS320LF2407A. It can be seen from the experimental data and experimental wave that it can effectively restrain the ring current and achieve the equipartition of load in the condition of resistive load and inductive load or capacitive load to achieve the data communication among the parallel inversion modules.
