    摘要: A device includes a controller that receives current values generated by at least four parallel load commutated inverters (LCIs) 12. The controller includes a source firing generator 60 that generates independent source firing commands for each of the at least four parallel LCIs 12 based on the received current values and transmits each of the independent source firing commands to a respective one of the at least four parallel LCIs, wherein the source firing commands are configured to set input phase angle values of the four parallel LCIs 12.
