摘要： A control and protection system has a DC terminal (DCT), for connection to a DC bus (DCB), a load terminal (LT) for connection to a LOAD, a ground terminal (GT) for connection to an external ground bus (EGB), and an INPUT terminal for receiving ON/OFF commands. An internal ground bus (IGB) of the system is normally coupled to the EGB via the GT. But if a ground fault disconnects the GT from the EGB, the system automatically couples the IGB to the LT, thereby providing a synthetic ground that facilitates continued operation of the system and any peripheral circuits coupled between the DCB and the GT. Any peripheral circuit current passing through the system to the EGB is prevented from causing improper operation of the LOAD by automatically adjusting a series impedance that it passes through between the GT and the LT before reaching the LOAD and EGB.

摘要： A low drop-out DC voltage regulator comprising an output pass element for controlling an output voltage (v) of power supplied from a power supply through the output pass element to a load (R), a source of a reference voltage (v), and a feedback loop for providing to the output pass element a control signal tending to correct error in the output voltage. The feedback loop includes a differential module responsive to relative values of the output voltage (v) and the reference voltage (v) and an intermediate module driven by the differential module for providing the control signal. The differential module presents the widest bandwidth of the modules of the regulator and the differential module presents a frequency pole that is higher than the cut-off frequency of the regulator, at which its regulation gain becomes less than one.
