Disclosed is a power supply system (50) comprising a power supply circuit (1), a sensor (3) of a current (IHV +) flowing through terminals of the power supply circuit, and a protection circuit (2). The protection circuit comprises a differentiator (2-1; 2-2) adapted to measure the slope of the current measurement signal (S1ms). 2-1, 2-2, 2-3) and comprising a drive stage. The power supply circuit (1) is configured to receive the disconnection signal (S1dsn), and alternatively, according to a value of the disconnection signal (S1dsn), an internal component of the power supply circuit is electrically connected to a terminal of the power supply circuit or an internal component of the power supply circuit is electrically disconnected from the terminal of the power supply circuit.
公开了一种电源系统(50),其包括电源电路(1)、流经电源电路的端子的电流(I_HV+)的传感器(3)和保护电路(2)。保护电路包括适于测量电流测量信号(S1_ms)的斜率的微分器(2‑1;2‑2,2‑3),并且包括驱动级。电源电路(1)被配置成接收断开连接信号(S1_dsn),并且可替代地,根据断开连接信号(S1_dsn)的值,将电源电路的内部部件电连接到电源电路的端子或者将电源电路的内部部件与电源电路的端子断开电连接。
