Abstract: Methods, systems, and devices for fault detection at pulse width modulation converters are described. An example of one such method includes receiving a first signal including a first pulse width modulation waveform. The first signal may be for controlling a switching component via a first node. A second signal may be received. The second signal may include a second pulse width modulation waveform. The second signal may be output by a second node of the switching component. One or more operations may be performed to compare the second signal with one or more other signals or one or more thresholds. A third signal may be transmitted based at least in part on the comparison of the second signal with the one or more other signals or thresholds. The third signal may indicate whether a fault has occurred at the switching component.
