Adaptive error amplifier clamping in a multi-feedback loop system
摘要:
The present document relates to power converters with multiple feedback loops. The present document relates to a power converter with at least two feedback loops. The power converter may include a first error amplifier configured to generate a first error signal based on a first reference signal and a first feedback signal. The power converter may include a second error amplifier configured to generate a second error signal based on a second reference signal and a second feedback signal. The power converter may include a selector circuit configured to generate a selection signal by selecting the first error signal or the second error signal. The power converter may include a first clamp circuit configured to limit the first error signal to a first threshold value. The power converter may include a first threshold value generator circuit configured to generate the first threshold value dependent on the first error signal.
