  • Patent number: 10050540
    Abstract: A protection circuit for a power converter is provided. The protection circuit includes a sensor circuit, a detection circuit and an initial protection circuit. The sensor circuit senses an output current of the power converter to generate a load signal. The detection circuit detects a voltage signal at a signal terminal of the connection port. The initial protection circuit compares the load signal with an initial-protection threshold. When the voltage signal at the signal terminal switches to a high level from a low level after the protection circuit is enabled, the power converter enters an initial protection mode and the initial protection circuit counts an initial period of a port-identification procedure. When the load signal is larger than the initial-protection threshold during the initial period of the port-identification procedure, the initial protection circuit generates a first protection signal to shut down the power converter.

  • Patent number: 9825543
    Abstract: A power converter and a control method therefor are provided. The power converter includes a transformer, a primary-side control circuit and a secondary-side control circuit. A primary side of the transformer receives an input voltage, and a secondary side of the transformer generates an output voltage. The primary-side control circuit controls a current switch of a primary winding and switching thereof. The secondary-side control circuit is disposed at the secondary side of the transformer. The secondary-side control circuit comprises a latch circuit. The latch circuit clamps a feedback signal and maintains a clamped status of the feedback signal when an fault event occurs. The primary-side control circuit stops switching the current switch of the primary winding when the feedback signal is clamped, and the latch releases the feedback signal when the output voltage is lower than a default latch voltage value.
