Abstract :
Studied the components´ affect to the high-capacity multi-DC converter system, through theoretical analysis and simulation, the author discussed the system´s operation state when the inductance, capacitance, IGBT, freewheeling diode respectively went wrong. Then got the conclusion, when there is a fault in the parallel system, the output voltage and current will be lack phase, ripple excessive, current discontinuous and so on.
