Abstract
A regulation method for current limiting control, comprising: S. regulating a current limiting threshold in real time based on a current limiting action: S. controlling switch transistors based on the regulated current limiting threshold. By implementing the regulation method and device, it is made possible to regulate a current limiting threshold in real time directly based on a current limiting action, such that a current uprush in a first PWM wave will be significantly suppressed at the time of sudden loading or occurrence of a short circuit. Further, by regulating the current limiting threshold in real time based on the current limiting action and an inductive current, it is not only made possible to satisfy proper load-carrying capability, but also made possible to prevent a current uprush in a first PWM wave from being too high at the time of sudden loading or occurrence of a short circuit.
