Embodiment Construction
[0017] The core idea of the present invention is: when the power supply is initially powered, the current limiting unit is used to limit the maximum current allowed to flow in, which avoids the impact of the impact current of the board when the board is powered on; at the same time, the switch unit is used to allow a large current to pass, thereby ensuring normal The current required for work, because the current limiting unit only works when the power supply is initially powered on, the loss caused by current limiting is negligible, and the static loss of the switching unit is very small, so the loss of the entire slow start circuit is very small. In addition, the capacity of the energy storage unit is not limited, so that the board can provide an energy storage unit of any capacity according to actual needs.
[0018] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.
