摘要： A circuit for suppressing transients in a voltage regulator due to a load step transient in the demand of the load. The circuit includes a suppressor element that is placed in the current path of the inductor of the switching regulator in response to a determination of an over voltage condition. The suppressor element pulls the voltage level of one side of the inductor below a particular potential, such as, e.g., system ground. Examples of suppressor elements that may be used include zener diodes, diodes, capacitors, resistors, and negative voltage sources. When the current through the inductor has subsided to a particular level, the suppressor element may be removed from the inductor current path, wherein the energy stored in a bulk filter capacitor may be drained through the inductor to the system ground. The suppressor circuit may be used in a information handling system or other type of electronic system.

摘要： A clamping circuit and method for use in a computer system are provided. In the computer system, a voltage regulator supplies a voltage rail to various components in the system. This voltage rail may be susceptible to voltage spikes or other over-voltage conditions, such as when the voltage rail provides the input voltage to a switching regulator. The clamping circuit comprises a detecting stage and a clamping stage. The detecting stage detects when the voltage rail increases beyond a first voltage level. If this increase is detected, the detecting stage activates the clamping stage, which begins reducing the voltage rail. Once the voltage rail decreases beneath the first voltage level, the detecting stage stops activating the clamping stage. In this way, the clamping circuit protects the computer system from voltage spikes on the voltage rail.

摘要： A power module including a self arc-extinguishing type semiconductor such as an IGBT and having a function to protect the semiconductor, i.e., to protect the IGBT against a short-circuit current. Even the IGBT having a collector-emitter saturation voltage VCE (sat) set low can be protected against the short-circuit current, by charging a collector-gate junction capacitor (13) quickly, when a sense current IS to flow through a current sense exceeds a set value, to raise a collector voltage VCE quickly thereby to prevent a collector current IC from increasing, by keeping a gate voltage VGE of the IGBT (12) at a voltage rather higher than a threshold voltage, and by turning OFF the IGBT (12) after a predetermined time.

摘要： A vehicle power system includes a multiple of electrical generators which provide power for vehicle electrical systems or loads through an electrical load management center which communicates with a general purpose processor set such that the power supplied to each electrical load may be individually controlled. A display communicates with the GPPS to present an electrical system status screen to the vehicle crew such that the crew is constantly made aware of the prevailing electrical power conditions in a rapid and efficient manner. During a drastically reduced generator situation, the GPPS automatically disconnects loads via a predefined load shed priority list. Once electrical loads are disconnected via the predefined load shed priority list the crew can reactivate and deactivate selected systems for the current mission circumstances through a load recovery screen accessible through the display.

摘要： A failure detection scheme for switching voltage regulators senses a parameter which normally transitions above and below a predetermined threshold during each clock cycle. A decision circuit tracks the sensed parameter, and toggles an output when the sensed parameter transitions normally. A counter counts clock cycles, and toggles its output when a predetermined number is reached. The counter also has a reset input which receives the output of the decision circuit, and is reset to an initial value when the decision circuit output toggles. If the sensed parameter fails to transition normally, the reset input is not toggled and the count value increments with each clock cycle. If the failure persists for the predetermined number of clock cycles, the counter output toggles to indicate a failure, enabling the failed regulator to be repaired or replaced before additional failures occur.

摘要： A method for performing a short-circuit and overload disconnection with a semiconductor component includes the steps of providing a semiconductor component having a drain, a source and a gate. The semiconductor component has a gate-source voltage applied thereto, a current flowing therethrough, and a voltage dropping between the source and the drain. The gate-source voltage at the semiconductor component is adjusted, in dependence of the current flowing through the semiconductor component, such that, after charge carriers in the semiconductor component are depleted, the voltage dropping between the source and the drain assumes a highest possible value still uncritical for the semiconductor component and for a circuit to be disconnected. An algorithm is used for the step of adjusting the voltage dropping between the source and the drain. The apparatus for carrying out the method uses of a processor for ascertaining and processing measured values and for performing the short-circuit recognition and the disconnection.

摘要： A voltage regulator protecting both the regulator and the electrical system. A flyback diode is protected by an autoprotected MOSFET in series with the flyback diode and controlling it by a drive circuit connected to the vehicle ignition switch. Protection against overcurrent is provided by a resettable fuse, having a thermal protection circuit, in series with the power switch. A relay is in series with the resettable fuse. The controlled switch is controlled by the output of a voltage detector. A latching circuit holds it open as long as the circuit remains connected to the battery. Overvoltage protection is provided by a voltage detector which opens the relay if the battery voltage exceeds a pre-selected voltage. To accommodate lead-acid and maintenance-free batteries, the regulator has two input ignition terminals one of which controls the set point voltage. The resettable fuse is physically mounted in thermal connection to the power switch which switches the field.

The power supplies typically comprise a redundant system for maintaining availability of bus voltage in the event of the failure of one of the supplies. The circuitry provides advantages in high power applications over prior art by overcoming the inefficiencies of connecting the supplies to a common bus through a diode.
