Abstract: A multipin matrix capacitor includes a first and second electrode separated by a dielectric material to form a capacitive element and includes terminals for connecting it to the first and second electrode wherein the terminals are distributed along the electrodes in a grid arrangement. Inductances are minimized or substantially eliminated in lead connections to the matrix capacitor due to the reduced conduction path lengths possible between an external component and the capacitor since access to the capacitor is provided at substantially all areas of the electrodes forming the capacitor. In one aspect of the invention, DC current is conducted along the surface of conductive sheets comprising the electrodes.

Abstract: A switched-capacitor circuit has two capacitors and two MOSFETs that cross-couple the capacitors, connecting the anode of one to the cathode of the other, and vice-versa. When either MOSFET is on, the capacitors are in series; the order alternates as the MOSFETs alternate. A reversing cyclical voltage suitable as a primary drive for a transformer is generated. If the MOSFETs alternate with no dead-time, a square-wave excitation is generated. With off-time, a pwm excitation is generate. Charge is maintained on the switched-capacitors using a symmetrical common-mode inductor. A bifilar winding is center-tap as its input, and the ends of the bifilar winding are connected to the capacitors. The capacitors are effectively in parallel. Because the charging current flows and returns through each leg of the inductor equally, it cannot magnetize the inductor core or cause any flux change. Because any voltages induced in the windings are common-mode, flux change in the core does not affect the charging current. The ac voltage generated when the capacitors switch is across the full inductor. Not only does the inductance attenuate any noise, the center-tap is between equal and opposite negative and positive voltages, which cancel. There is very little noise at the input. The circuit is reciprocal, so it can be used to rectify a transformer output. Two can be used as a bi-directional transformer isolated power converter. Several modules using 1 to 1 transformers can be stacked for a power converter having a higher ratio of input to output voltage.

Abstract: Linear regulators are inexpensive and provide excellent control with a very fast frequency response while avoiding many of the problems of pulse-width-modulated (pwm) regulators. However, they are seldom used due to their very poor efficiency. Not only do the losses in the regulator reduce the efficiency, resulting in higher energy costs, the heat in the controller is a significant problem. By co-locating the linear regulator with the heater, immersed in the medium to be heated, the losses of the linear regulator contribute to the heat to the medium, and net efficiency is nearly 100 percent. It is not necessary to co-locate the entire control, as the high dissipation likely is limited to the power transistors and only they need to be co-located with the load.

Abstract translation: 线性稳压器价格便宜，提供了极好的频率响应控制，同时避免了脉冲宽度调制（pwm）调节器的许多问题。 但是，由于效率非常差，所以很少使用。 调节器中的损耗不仅降低了效率，而且导致更高的能源成本，控制器中的热量也是一个重大问题。 通过将线性调节器与加热器共同定位，浸入待加热的介质中，线性调节器的损耗有助于介质的热量，净效率接近100％。 由于高耗散可能仅限于功率晶体管，并且仅需要与负载共同定位，因此无需对整个控制进行共同定位。

Abstract: A power factor corrected (pfc) ac-dc converter has a modified boost input and a modified buck output. Unlike the prior art boost input, the boost switch returns to the output, not to ground. Unlike the prior art buck output stage, a third switch connects to the input. This allows much of the input current to pass through the converter to the output. There is no input current measurement, but nearly ideal power factor correction is achieved through “natural modulation.” A preferred pfc ac-dc converter uses a variable dc-dc transformer on its output, as a post regulator, to provide dielectric isolation and to provide voltage level shifting. The output of the pfc ac-dc converter has the control characteristics of a buck converter, so it is a natural mate for the variable dc-dc transformer. An ac-dc buck converter is most efficient at its maximum duty cycle. It cannot regulate for a lower input voltage, but it can reduce its duty-cycle to control for higher input voltages. A variable dc-dc transformer is most efficient at its maximum ratio. It cannot regulate for a higher input voltage, but it can reduce its effective turns ratio to control for a lower input voltage. With a small overlap in their control ranges, both parts of the power system can operate at maximum efficiency. The variable dc-dc transformer controls the output voltage for nominal and low input voltage. The ac-dc buck converter limits over-voltage transients.

Abstract: A fastener for splicing wires and the like is mace by forming a tubular sleeve of spring material such as phosphor bronze. In its unrestrained shape, the tubular sleeve is too small to receive the wires, but the tubular sleeve is expanded elastically and held expanded by solder, so that the wires can be inserted. Upon the application of heat the solder melts, flowing into the joint and allowing the sleeve to spring back to its original size or at least to the diameter of the wires. The fastener can be mounted on a stud to provide a replacement for the familiar solder cup terminal. An expanded sleeve can be placed around a piece of heat shrinkable tube. When heated, the tube and the sleeve contract, the sleeve reinforcing the tube giving a much greater compressive force during shrinking. The sleeve then becomes a metallic protector for the tube.

Abstract: A DC-DC power converter, which can be adapted for use with a single- or multiple-phase AC input, uses energy control because it transcends the modulators and is linear. The use of feed back control is minimized by the use of feed forward control, and in particular the feed forward of the output power to control the input power. The dynamic resistance of the input is controlled, ensuring high power factor in the AC input embodiments of the converter. A multiple-input buck derived converter can have parallel or series inputs, and one or more of the inputs can be lower than the output, even zero or negative. A multiple output boost derived converter can have parallel or series outputs, and one or more of the outputs can be lower than the input, even zero.

Abstract: A DC-DC power converter adaptable for use with an AC input, uses feed forward control of the output power to control the input power and the dynamic resistance of the input to ensure a high power factor in the AC input embodiments of the converter. The dynamic response of the power converter is controlled by feed forward, either through scheduling the energy content of a storage capacitor as an explicit function of the output power, the input voltage and the time constant, or through energy deficit feed forward in which the energy deficit caused by a transient is fed forward as an increment of power under feed forward control. Line frequency ripple feed forward compensates the feed forward in the embodiments having an AC input for any half frequency harmonics present in full wave rectified input due to a DC offset or asymmetry in the AC input. With load anticipation feed forward control, input power transitions smoothly without overshoot for a step change of output load from no load to full load and back.

Abstract: A high frequency matrix transformer comprises a plurality of interdependent magnetic elements interwired as a transformer. The various component parts of the high frequency transformer are arranged and interwired to provide a transformer having very low leakage inductance and very good coupling from the primary to the secondary. The high frequency matrix transformer is particularly well adapted for transformers requiring high equivalent turns ratios, high frequency, high power, and high dielectric isolation. It can have a plurality of parallel secondaries, which can source current to parallel rectifier circuits with current sharing. It can also have a plurality of parallel primary circuits, which also will current share, to balance the load between source switching circuits, or to provide dual input voltage capability (i.e., 120/240 volts). The high frequency matrix transformer tends to be spread out, and can be very flat, making it easy to ventilate or heat sink. The high frequency matrix transformer having push pull windings can include the primary switching device and secondary rectifying device within its windings, so that the transformer as a whole has direct current inputs and outputs.
