Abstract
On the basis of analyzing the generation mechanism of inverter parallel system circle current, this paper brings forward a sort of balancing current strategy where the feed forward of average load current is externally added to the negative feedback of circle current, and by adjusting the feedback coefficient, the current impedance is increased in the condition of system output characteristics being constant, thus reducing effectively the circle current resulted from amplitude differences while the inverter operating in parallel. By utilizing TMS320LF2407A chip to implement the communication between the parallel system digital control and CAN bus, the anti-jamming and reliability of parallel system are improved. By Matlab simulations and experiments with two 1.5kw inverters in parallel, it is proved that the parallel system is of very nice dynamic response and current balancing effect in the case of linear load.关键词
