Frequency control of hysteretic power converter by adjusting hystersis levels |
摘要 |
A power converter is comprised of a hysteretic controller including a feedback circuit that monitors the output frequency of the controller, compares it to a reference generated either internally or externally by the user, and then adjusts the hysteresis of the controller accordingly. The adjusted hysteresis levels will then cause the switching frequency to either increase or decrease thereby controlling the switching frequency of the power supply controller and maintaining it at a desired level.
