开关保护电路和储能电源
By introducing protection and drive modules into the power supply circuit, the disconnection action of the power supply switch is delayed, which solves the problem of short power supply switch life, realizes protection of the power supply switch and load under high current, and improves the reliability of the power supply circuit.

AI Technical Summary
In existing technologies, the method of controlling the power supply switch to disconnect via a controller results in a short lifespan for the power supply switch, especially under high current conditions, which can easily lead to contact burnout and adhesion.
A protection module and a drive module are introduced into the power supply circuit. After the controller outputs the disconnect control signal, it delays for a first time period before performing the disconnect action. The protection module completes overcurrent protection before the duration of the received disconnect control signal exceeds the first time period, ensuring that the power supply switch disconnects only when the current is within the preset current window.
By delaying the disconnection action, the power supply switch is prevented from disconnecting directly under high current, which improves the lifespan of the power supply switch, reduces the risk of load damage, and enhances the reliability of the power supply circuit.
