ELECTROMAGNETIC INTERFERENCE (EMI) REDUCTION IN INTERLEAVED POWER CONVERTER |
| 摘要 |
A power converter system includes an interleaved power converter having a plurality of parallel-connected phase legs between DC terminals and an AC terminal. A plurality of parallel-connected inductors are each connected to one of the plurality of parallel-connected phase legs to provide a summed output of the parallel-connected phase legs to the AC terminal. A controller generates PWM signals used to control the state of each of the plurality of phase legs by comparing a carrier signal to a reference signal, wherein a period of the carrier signal is randomly varied from a nominal period. |

1. A power converter system comprising:
an interleaved power converter having a plurality of parallel-connected phase legs connected between direct current (DC) terminals and an alternating current (AC) terminal; a plurality of parallel-connected inductors each connected to one of the plurality of parallel-connected phase legs to provide a summed output of the parallel-connected phase legs to the AC terminal; and a controller that generates pulse-width modulation (PWM) signals used to control the state of each of the plurality of phase legs by comparing a carrier signal to a reference signal, wherein a period of the carrier signal is randomly varied from a nominal period. |
