An aspect of the disclosure provides a high frequency alternating current (HFAC) power distribution system configured to provide an HFAC power supply on an HFAC power supply bus to enable a plurality of electronic devices to be connected to the power supply bus for receiving HFAC electrical energy, the power distribution system comprising: an HFAC power supply configured to provide HFAC electrical energy to the HFAC power supply bus and having power supply output terminals for coupling to said bus; a protection circuit connected to the power supply and being arranged to provide a short circuit of the power supply; a power supply inhibitor operable to disable the power supply to prevent the provision of electrical energy; a detector circuit, configured to monitor gamma radiation to provide a detection signal; and a controller configured to operate the power supply inhibitor to prevent the provision of electrical energy in the event that the detection signal exceeds a threshold and then subsequently to operate the protection circuit to provide the short circuit.
A high frequency alternating current ( HFAC) power distribution system configured to provide an HFAC power supply on an HFAC power supply bus to enable a plurality of electronic devices to be connected to the power supply bus for receiving HFAC electrical energy, the power distribution system comprising:
The system of any preceding claim wherein the protection circuit comprises an electronic crowbar.
The system of any preceding claim wherein the controller is configured to operate the protection circuit to remove the short circuit prior to operating the power supply inhibitor to reenable the provision of electrical energy by the power supply.
The electronic device of any preceding claim wherein the HFAC power supply comprises an active element configured to drive an inductive circuit to oscillate to provide said HFAC electrical energy, and the power supply inhibitor is configured to disable said active element.
An electronic device comprising a circuit board, the circuit board comprising:
The electronic device of any preceding claim wherein the detection signal is further based on sensing low frequency current in an alternating current, AC, supply to the HFAC power supply.
