Ntc soft start
Web18 aug. 2024 · Switching converters on applications demanding reduced output noise may encounter delayed startup, or may not startup at all, due to excessive output inrush. Output inrush current, attributed to inappropriate design of output filters and its impact, can be minimized by increasing the soft start time, increasing the switching frequency, or ... WebSoft start is the gradual turning on of an electronic power supply to avoid stressing the components by the sudden current or voltage surges associated with the initial charging of capacitors and transformers. The …
