Title: DIRECT CURRENT-TO-DIRECT CURRENT CONVERTER AND FAULT PROTECTION METHOD
Abstract:
A direct current-to-direct current converter (300) and a fault protection method. The fault protection method is executed by the direct current-to-direct current converter (300). The method comprises: a controller detects, by means of a control port, whether a fault has occurred on an upper MOSFET (S701); and when the controller detects that a fault has occurred on the upper MOSFET by means of the control port, the controller switches off the MOSFET for protection by means of an output end (S702). The method aids to reduce a possibility that a load connected to the output end of the direct current-to-direct current converter (300) is damaged.
