    摘要： An insulation displacement contact block comprising a base and first, second, and third walls extending upward from the base. The first and second wall define a first wire insertion opening. The second and third wall define a second wire insertion opening. A first insulation displacement contact is disposed between the first and second wall, the first insulation displacement contact including a first side and a first edge, the first side being longer than the first edge. A second insulation displacement contact is disposed between the second and third wall, the second insulation displacement contact including a second side and a second edge, the second side being longer than the second edge. The first and second insulation displacement contacts are disposed so that the first edge faces, and is in the same plane as, the second edge. A plurality of insulation displacement contact blocks may be grouped together by a tie bar to form a strip.

    摘要： An electric device capable of handling high speed data communication and which could be used with, for example, a connector application such as an RJ45 type connector. The electric device is formed by inserting at least one wire through a first hole in a core, wrapping the wire around a side of the core, and inserting the wire through a second hole in the core a desired number of times. A common mode choke may be combined with the electric device. To form such a choke, two of the wires from the electric device may be wrapped around a second core in the same fashion a desired number of times.

    摘要： A power supply includes signaling circuitry coupled to output terminals for engaging in bidirectional communications with a load. A controller is capable of conducting the bidirectional communications and selecting among different operating modes for the power supply based on the communications. The modes may include a constant-current mode suitable for applications such as battery charging and power LED lamps, and a constant-voltage mode suitable for a variety of conventional uses such as powering electronic circuitry. The signaling circuitry may include a power switching transistor in series with the load, which is pulsed in a binary fashion to transmit communications to the load. A signal-forming resistor in parallel with the power switching transistor develops a signaling voltage monitored by the controller to receive communications from the load.

    摘要： A power converter includes a power transformer, primary-side circuitry connected between a power source and a primary coil, and secondary-side circuitry connected between secondary coil(s) and a load to generate an output voltage and load current for a load. The secondary-side circuitry includes (i) an output inductor, (ii) one or more power transistors, and (iii) control circuitry generating switching signals to operate the power transistors as synchronous rectifiers. The control circuitry (a) senses an inductor current in the output inductor, and (b) selectively disables the switching signals to the power transistors when the inductor current is less than a threshold current value in a range between a minimally negative value and a minimally positive value, the minimally negative value just preventing diode rectification mode of operation of the power transistors, the minimally positive value just preventing negative inductor current in the output inductor.

    摘要： A switched-mode power supply in a set of parallel-connected switched-mode power supplies is operated to (1) monitor both output current and operating temperature, and (2) autotune an output voltage using two-dimensional control that employs a two-dimensional function of the output current and the operating temperature. The two-dimensional function is a sharing function whose use in each of the supplies effects a coordinated sharing of both load current and operating temperature across the set of supplies. Temperature sharing includes monitoring and controlling distribution of operating temperatures across the set of supplies to reduce undesirable temperature imbalance that can cause excessive thermal stress and reduce reliability.
