Phase Current Estimation for Switching Power Converters |
| 摘要 |
A phase current estimator for a switching power converter includes analog circuitry for generating a phase current estimate error by comparing a phase current of the switching power converter to an analog representation of an estimate of the phase current, the phase current having a sawtooth or triangular waveform. The phase current estimator further includes digital circuitry for revising the phase current estimate based on the phase current estimate error and a plurality of parameters associated with operation of the switching power converter, so that the phase current estimate tracks the sawtooth or triangular waveform of the phase current. |

1. A phase current estimator, comprising:
analog circuitry operable to generate a phase current estimate error by comparing a phase current of a switching power converter to an analog representation of an estimate of the phase current, the phase current having a sawtooth or triangular waveform; and digital circuitry operable to revise the phase current estimate based on the phase current estimate error and a plurality of parameters associated with operation of the switching power converter, so that the phase current estimate tracks the sawtooth or triangular waveform of the phase current. |
