Embodiment Construction

[0050] "First", "second" and "third" in this embodiment of the present application are only used to distinguish different objects. Not used to limit the order of the different objects. For example, the embodiments mention a first switch, a second switch and a third switch. The first switch and the second switch are not the same switch. The second switch and the third switch are not the same switch. The first switch and the third switch are not the same switch.

[0051] figure 1 It is a schematic diagram of an application scenario provided by the embodiment of this application. Such as figure 1 In the system shown, a voltage converter 110 and a load 120 are included. The voltage converter 110 includes a control circuit 111 and three phases. The first phase 112 includes a first switch 115 and an inductor L1 coupled to the first switch 115 . The second phase 113 includes a second switch 116 and an inductor L2 coupled to the second switch 116 . The third phase 114 include...

Abstract

The invention provides a voltage converter fault processing method and a voltage converter The voltage converter comprises a control circuit and N phases. The control circuit controls N switches in the N phases to output N electric pulses in a first period, the first period is composed of N continuous sub-periods, each sub-period in the N continuous sub-periods has a time length of T1 / N, and N initial time of the N electric pulses are respectively N initial time of the N continuous sub-periods. The control circuit determines a first-phase fault. Furthermore, the control circuit controls N-1 switches of N-1 phases, apart from the first phase, among the N phases to output N-1 electric pulses in a second period. The second period is composed of N-1 continuous sub-periods, each sub-period in the N-1 continuous sub-periods has a time length of T2 / (N-1), and N-1 initial time of the N-1 electric pulses are respectively N-1 initial time of the N-1 continuous sub-periods.

Description

technical field [0001] The invention relates to the field of circuits, in particular to a voltage converter fault handling method and a voltage converter. Background technique [0002] A voltage converter (English: voltage converter) is a device capable of voltage conversion. A voltage converter can supply power to the load. The voltage converter may include multiple phases (English: phase), and the multiple phases all supply power to the load. When one phase of the voltage converter fails, the entire voltage converter cannot function properly. Contents of the invention [0003] Embodiments of the present application provide a voltage converter fault handling method and the voltage converter, which can handle the fault when a phase of the voltage converter fails. [0004] The technical scheme provided by the embodiments of the present application is as follows: [0005] In a first aspect, a voltage converter fault handling method is provided, the voltage converter incl...
