摘要： Method and apparatus for providing alternate current paths to a junction through different sets of gate controlled SCRs coupled to the junction. The method starts with the step of initiating a switch from an active set of SCRs to an inactive set by removing a gate signal from two parallel connected, opposite sense current carrying SCRs which in combination carry AC current in either direction. Removal of the gating signal is often initiated, for example, in response to an indication that one alternating current source is faulty so that a switch to a second source is initiated. Current is then sensed through the two SCRs of the active set to determine a current carrying state for each of those two SCRs. After the state of the current carrying SCRs is determined the current carrying state of the SCRs is confirmed during a delay time period. If the current carrying state of either of said two SCRs is the same during the delay time period, a gating signal is applied to a corresponding SCR in an inactive set to enable current flow through that corresponding SCR. Once both SCRs in the inactive set have been activated the switch is complete. By waiting until the current has been confirmed during the delay period inappropriate activation of the gate signals of an inactive switch is prevented.

摘要： A system and method are provided for using a multiple cell power supply in an implantable medical device such as an implantable cardioverter defibrillator. In a two-cell battery network, a higher energy density cell continuously charges a lower density cell, and the lower density cell provides the current needed for device functions. A current sensor detects the current flowing between the two cells. If the current deviates from an acceptable normal range, one battery cell is failing. The battery network is then reconfigured by opening and closing intervening switches such that the failing cell is eliminated and the remaining cell continues to power device functions. Upon eliminating a failing battery cell, a patient warning signal is issued.

摘要： In an electric power system interconnection device, a primary power supply is connected to a load via a switch and a secondary power supply is connected to a load side of the load via a power converter to establish coordinated interconnection of the primary power supply and the secondary power supply. When the switch is opened in the event of a failure of the primary power supply, the electric power system interconnection device extinguishes an arc current flowing through the switch, at a high speed, by controlling an output current of the power converter using the load current flowing into the load as an output current command for the power converter so that uninterrupted electric power is supplied to the load.

摘要： An apparatus and method for switching between two power supplies, a primary power supply and a secondary power supply. The present invention generates a first reference voltage using the voltage of the primary power supply and the secondary power supply, wherein the primary power supply voltage is variable. The present invention also generates a second reference voltage based on the voltage of the primary power supply. The first and second reference voltages each have a different slope and the crossing point between these two reference voltages indicate that a switch between the primary power supply and the secondary power supply should occur.

摘要： An OR circuit allowing one stable output voltage from a plurality of input voltages is disclosed. A first FET is connected between a corresponding input terminal and an output terminal in such a manner that an inherent diode of the FET is connected in a forward direction. A second FET is connected between a corresponding input terminal and the output terminal in the same manner as the first FET. Each of the input voltages is compared with the output voltage. The conduction/non-conduction states of each of the first and second FETs are independently controlled depending on the comparison result.

摘要： A transfer mechanism is provided for transferring the supply of power between a generator and utility source. The transfer mechanism includes a monitoring system for monitoring the power supplied by the utility source. The monitoring system starts the generator in response to a power outage from the utility source and stops the generator in response to the restoration of power from the utility source. A power relay has a utility input connectable to the utility source, a generator input connectable to the generator, an output connectable to a load, and a movable contact for selectively interconnecting one of the inputs to the output in response to the generation of power by the generator.

摘要： A method and apparatus for switching at least one alternatingcurrent load from one power supply, such as a voltage supply or current supply, to another power supply, such as a voltage supply or current supply, upon the appearance of an error in the power supply coupled with the load. Each power supply possesses electronic switch means at the connection conductors to the load. An error detector determines the deviations of the waveshape of the load voltage from a predetermined waveshape of a reference voltage for a successive time interval, and upon exceeding an adjustable maximum deviation value, the electronic switch means are actuated for coupling the first-mentioned power supply to the other power supply.
