摘要： In methods and circuits for using associated circuitry to enhance performance of a micro-electromechanical switch, one of the method embodiments is a contact conditioning process including applying a time-varying voltage to the control element of a closed switch. In another embodiment, a voltage profile applied to the control element of the switch can be tailored to improve the actuation speed or reliability of the switch. In another method embodiment, the performance of a switch may be evaluated by measuring a performance parameter, and corrective action initiated if the switch performance is determined to need improvement. An embodiment of a circuit for maintaining performance of a micro-electromechanical switch includes first and second signal line nodes, sensing circuitry coupled to the signal line nodes and adapted to sense a performance parameter value of the switch, and control circuitry operably coupled to at least one terminal of the switch.

摘要： A low power consumption switch interface circuit (100) includes a current source (109) for providing switch current (144) having a magnitude dependent on a state of a current range signal (135). An input terminal (142) is provided to conduct the switch current (144) to an external switch (102). A circuit (101, 103, 119) for detecting a signal (141) present at the input terminal (142) provides a measured pulse (127) when the signal (141) is detected. A current range selector (129), coupled to the current source (109), outputs a first state of the current range signal (135) while the measured pulse (127) is outputted from the circuit (101, 103, 119), and a second state of the current range signal (135) while the measured pulse (127) is not outputted from the circuit (101, 103, 119). The current source (109) provides the switch current (144) at a first magnitude responsive to the first state of the current range signal (135), and a second magnitude responsive to the second state of the current range signal (135).

摘要： A computer bus structure is provided which permits replacement of removable modules during operation of a computer wherein means are provided to precharge signal output lines to within a predetermined range prior to the usage of the signal output lines to carry signals, and further, wherein means are provided to minimize arcing to pins designed to carry the power and signals of a connector. In a specific embodiment, pin length, i.e., separation between male and female components of the connector, are subdivided into long pin length and short pin length. Ground connections and power connections for each voltage level are assigned to the long pin lengths. Signal connections and a second power connection for each voltage level is assigned to the short pin lengths. The precharge/prebias circuit comprises a resistor divider coupled between a power source and ground with a high impedance tap coupled to a designated signal pin, across which is coupled a charging capacitor or equivalent representing the capacitance of the signal line. Bias is applied to the precharge/prebias circuit for a sufficient length of time to precharge the signal line to a desired neutral signal level between expected high and low signal values prior to connection of the short pin to its mate.

摘要： A tap changer voltage regulator permits a tap changer switch selector contact to engage an open-circuited new tap without arcing and has a half-tap voltage auxiliary winding which permits halving the inter-tap voltage and doubling the number of steps, and also has an auxiliary switch system. An auxiliary static switch circuit initially connects a first tap selector in series with a circulating current limiting resistor and a load to prevent load circuit interruption. An auxiliary selector switch initially coupled to a second tap selector and is in series with a normally-closed switch through which the load current and circulative current flow. The normally-closed switch is shunted by a second static switch circuit. The first static switch is not gated until the first tap selector has attained its new position, precluding initial arcing. The normally-closed switch is then opened; subsequently gating current is removed from the second static switch so that load and circulating current are statically interrupted at current zero. The selector may then be arclessly disconnected from the second tap selector and moved to contact the first tap selector.
摘要翻译：分接开关电压调节器允许分接开关选择器触点接合没有电弧的开路新抽头，并且具有半抽头电压辅助绕组，其允许将分接头电压减半并使步数加倍，并且还具有辅助开关系统。辅助静态开关电路首先将第一分接选择器与循环限流电阻和负载串联连接以防止负载电路中断。辅助选择开关最初耦合到第二抽头选择器，并与常闭开关串联，通过该开关负载电流和循环电流流过。常闭开关由第二静态开关电路分流。在第一个分接选择器达到其新位置之前，第一个静态开关不会选通，排除初始电弧。然后打开常闭开关; 随后的门控电流从第二静态开关移除，使负载和循环电流在电流零点处静止中断。然后，选择器可以与第二抽头选择器无弧度地断开并移动以接触第一抽头选择器。
