摘要： A digital output circuit to be driven by an insulated power-supply circuit includes a transistor to turn on/off an external power supply in accordance with a signal output by a light receiving element in an insulating circuit in response to a signal processed by a controller. The external supply is connected to an output device. The output circuit includes a switching unit having first and second mechanisms to switch each of wires between a connected state and a non-connected state at two places between the light receiving element and the source or emitter of the transistor, and a logic adjusting unit to adjust inversion of a logic output of the light receiving element in correspondence to the type of the transistor, such that the output circuit is switched between a sink-current type and a source-current type.

摘要： A discharge device and method actively discharge a main capacitor in an electric-power system of an electric-drive vehicle. The discharge device comprises a discharge branch of a circuit that is connected in parallel to the main capacitor and includes a discharge transistor that is biased to “conduction” mode when the main capacitor is required to be discharged. A control device is connected to a “gate/base” terminal of the discharge transistor and commands the discharge transistor, biasing the discharge resistor to “conduction” mode when the main capacitor is required to be discharged. The control device includes a safety capacitor that is interposed between the “gate/base” terminal and a power supply and charges when the discharge transistor is in the “conduction” mode, causing a progressive decrease of current at the “gate/base” terminal, until the discharge transistor is biased to the “non-conductive” state.

摘要： A switching circuit for switching electric potentials, such as a capacitive high voltage load in an X-ray generator is structured into plural stages having an electronic switch, wherein the electronic switches of the different stages are arranged in series, in order to form a series conduction line for switching the electric potentials. The plural stages draw energy from the series conduction line during the time period when the series conduction line is blocked and charge an energy storage. This stored energy can be utilized for closing the series conduction line and maintaining this closed state. Further, disclosed is a method for discharging an electric load by means of a switching circuit. Also disclosed are a high voltage generator, an X-ray generator and a medical imaging system, each having such a switching circuit.
