Switched-Mode Power Conversion |
摘要 |
In accordance with an embodiment, a method of operating a switched-mode power converter includes driving a switching element in successive drive cycles, in which the switching element is driven to switch on for an on-period and subsequently driven to switch off for an off-period; sampling a feedback signal two or more times during the drive cycles, where the feedback signal includes a signal representative of an operation parameter of the switched-mode power converter and noise. The method further includes filtering the sampled feedback signal to extract the signal representative of the operation parameter from the sampled feedback signal and controlling the switching element according to the filtered feedback signal. |

1. A method configured to operate a switched-mode power converter, in which the power converter is operable to convert an input voltage into an output voltage at a switching frequency of a switching element in the power converter; the method comprising:
driving the switching element in successive drive cycles, in which the switching element is driven to switch on for an on-period and subsequently driven to switch off for an off-period; sampling a feedback signal two or more times during the drive cycles; the feedback signal comprising a signal representative of an operation parameter of the switched-mode power converter and noise; filtering the sampled feedback signal to extract the signal representative of the operation parameter from the sampled feedback signal; and controlling the switching element according to the filtered feedback signal. |
