    摘要: We describe a system for controlling very large numbers of power semiconductor switching devices (132) to switch in synchronisation. The devices are high power devices, for example carrying hundreds of amps and/or voltages of the order of kilovolts. In outline the system comprises a coordinating control system (110, 120), which communicates with a plurality of switching device controllers (130) to control the devices into a plurality of states including a fully-off state, a saturated-on state, and at least one intermediate state between the fully-off and saturated-on states, synchronising the devices in the at least one intermediate state during switching.

    摘要: We describe techniques suitable for communicating switching data in a control system controlling, for example, kilovolts at hundreds of amps. The system comprises a central controller (110) coupled to sub - controllers (120) and thence to a plurality of switching device controllers (SDs,130), preferably in a tree - structure, each SD controlling a power semiconductor switching device such as an IGBT. The method includes formatting switching control data as one or more switching control data packets comprising data for controlling switching of a combination of the devices, sending these from the central controller to the switching device controllers, at the SDs formatting state data representing states of the switching devices controlled in combination into a plurality of acknowledgement data packets, and sending these back to the central controller. The techniques may be employed for controlling the synchronised switching of, potentially, tens, hundreds or thousands of power semiconductor switching devices.

    摘要: We describe a controller (130) for controlling a power semiconductor switching device (132) into a selected one of a plurality of states, the states including a fully-off state, a saturated-on state, and at least one intermediate state. The switching device controller includes a voltage sense input (142) to sense a voltage on the device; a current sense input (current feedback) to sense a current passing through the device; a negative feedback control circuit (138) coupled to the sense inputs, a control output (136) to provide to the power semiconductor switching device a drive signal with a response dependent on one or more adjustable parameters; and a circuit controller (140) to control the adjustable parameters responsive to state command data, to control the switching device into a selected state, in particular by controlling an effective resistance of the device. Preferred intermediate states include an active low current state and an active low voltage state.
