    摘要： An electronic circuit for a surgical robotic system includes a central power node, a first voltage bus that electrically couples a first power source to the node, a second voltage bus that electrically couples a second power source to the node, and several robotic arms, each arm is electrically coupled to the node via an output circuit breaker and is arranged to draw power from the node. Each bus is arranged to provide power from a respective power source to the node and each bus has an input circuit breaker that is arranged to limit a first output current flow from the node and into the bus. Each breaker that is arranged to limit a second output current flow from the node and into a respective arm. A breaker is arranged to open in response to a fault occurring within the respective arm, while the other breakers remain closed.

    摘要： An over-voltage protection system for an accelerator can include: a plurality of DC power supplies configured to provide a plurality of voltage levels up to a desired voltage level; and an acceleration tube electrically connected to the plurality of DC power supplies and configured to accelerate a charged particle. The acceleration tube can include a plurality of stages. Each stage can include a plurality of electrodes and a plurality of varistors configured to discharge energy in response to an overvoltage event. One electrode of the plurality of electrodes can be electrically coupled to a voltage level of the plurality of voltage levels. The plurality of electrodes and the plurality of varistors can be electrically coupled to each other and arranged in an alternating fashion.

    摘要： Driver circuitry for driving a power semiconductor switch having a control input and main terminals is described. The driver circuitry includes control terminal driver circuitry coupled to the control input and configured to provide a drive signal, a sense terminal coupled to the main terminal, a current mirror coupled to the sense terminal to mirror a current input into the sense terminal during turn-off, a first current comparator configured to compare a current signal received from the current mirror to a first current threshold and output a first signal representative of the comparison, and a second comparator configured to compare a signal received from the sense terminal to a turn-on threshold and output a second signal representative of the comparison. The turn-on threshold represents a highest voltage of the main terminal during turn-on. The first current threshold represents a highest voltage of the main terminal during turn-off.
