Application of TMS320LF2407A and CAN Bus Technology in Flow Control of Inverter


Article Preview

As parallel operation of several single inverter modules, the alternating voltage outputted by the single inverter module should guarantee same frequency, same phase and equiamplitude. Otherwise, circumfluence will be caused in the single inverter module. The circumfluence not ecreases output capacity of the system but destroy the inverter in serious condition. So, restraint circulation is the key technology of inverter modules in parallel control. Based on the analysis of inverter modules in parallel control, this paper designs the parallel current sharing system of multi-inverter modules with TMS320LF2407A as the main hip, adopts the control strategy of “direct current sharing”, and achieves the data communication in multi-modules allel connection as well as the effects of multi-inverter odules in parallel current sharing control with CAN controller embedded in TMS320LF2407A.
