Abstract
An electrical supply system including a voltage converter including having an input electrically coupled to a supply for receiving a supply signal and an output for supplying an output signal having a output voltage different to a supply voltage of the supply signal. The system includes a diode including a diode input electrically coupled to the voltage converter output, a bus electrically coupled to a diode output and at least one of a load and a store, a voltage sensor for detecting the output voltage, a current sensor for detecting a diode input current and an electronic processing device coupled to the sensors for monitoring the diode input current and the output voltage and detecting a fault in the electrical supply system based on at least the diode input current and output voltage.
Claims11
An electrical isolator for isolating a power supply of an electrical supply system, the isolator including a voltage converter having:
- a) a voltage converter input electrically coupled to a supply for receiving a supply signal;
- and
- b) a voltage converter output for supplying an output signal, the output signal having a output voltage different to a supply voltage of the supply signal;
- c) a transformer;
- d) a switching circuit coupled to the voltage converter input and the transformer;
- and
- e) a controller configured to:
- i) detect an electrical fault in the electrical supply system;
- and,
- ii) control the switching circuit to thereby selectively apply the supply signal to a transformer input to thereby at least one of:
- (1) generate the output signal if no fault is detected;
- and,
- (2) electrically isolate the voltage converter input from the voltage converter output if a fault is detected.
