摘要： A Factorized Power Architecture (“FPA”) includes a power regulator providing controlled DC bus voltages distributed and converted to load voltages, at the load, using DC voltage transformation modules (“VTMs”) having fixed transformation ratios. Optional feedback from the load improves regulation. A Sine Amplitude Converter (“SAC”) VTM locks the conversion frequency to resonance of a resonant circuit including a transformer, uses complementary primary switches, balanced switching, and a high conversion duty cycle, and may use primary ZVS and secondary ZVS and ZCS, low Q, and a low profile core structure, and may exhibit greater than 400 Watts/cubic-inch power density and 95% efficiency. Common-source gate-control topologies efficiently drive switches higher than 1 MHz. Symmetrical power trains reduce common-mode noise. Modulated converter output resistance controls Vout, limits Iout, or improves current sharing. Gate drive circuitry recycles energy from the transformer magnetizing inductance. A DC—DC converter includes a non-isolated converter followed by a SAC.

摘要： An automated custom power supply design system uses an expert system containing a set of rules, including manufacturing limitations to limit design choices and ensure feasibility and manufacturability of the design. A design interface collects specifications from a user. A complement of power components for satisfying the electrical specifications is defined and mechanical specifications for each component are provided by the system for use in creating the mechanical design. After the mechanical design is established a thermal analysis is performed and the completed design is returned to a host computer. After an order is received, a computer integrated manufacturing system generates all of the specifications required to manufacture the components for the system and the system.

摘要： A method of forming a self-aligned electrical winding includes forming a first conductive turn in a first conductive layer around a planned leg hole and forming a second conductive turn in a second conductive layer around the planned leg hole. The method includes stacking a plurality of conductive layers aligned with each other, and separated from each other by at least one intervening insulation layer into a multilayer PCB stack. The method includes forming the planned leg hole through the multilayer PCB by removing the respective conductive portions of the first conductive turn and second conductive turn that extend into the planned leg hole. Forming the leg hole defines a first inner circumference for the first conductive turn and a second inner circumference for the second conductive turns, wherein the first inner circumference is aligned with the second inner circumference through forming the leg hole.

摘要： A method of encapsulating a panel of electronic components such as power converters reduces wasted printed circuit board area. The panel, which may include a plurality of components, may be cut into one or more individual pieces after encapsulation with the mold forming part of the finished product, e.g. providing heat sink fins or a surface mount solderable surface. Interconnection features provided along boundaries of individual circuits are exposed during the singulation process providing electrical connections to the components without wasting valuable PCB surface area. The molds may include various internal features such as registration features accurately locating the circuit board within the mold cavity, interlocking contours for structural integrity of the singulated module, contours to match component shapes and sizes enhancing heat removal from internal components and reducing the required volume of encapsulant, clearance channels providing safety agency spacing and setbacks for the interconnects. Wide cuts may be made in the molds after encapsulation reducing thermal stresses and reducing the thickness of material to be cut during subsequent singulation. External mold features can include various fin configurations for heat sinks, flat surfaces for surface mounting or soldering, etc. Blank mold panels may be machined to provide some or all of the above features in an on-demand manufacturing system. Connection adapters may be provided to use the modules in vertical or horizontal mounting positions in connector, through-hole, surface-mount solder variations. The interconnects may be plated to provide a connectorized module that may be inserted into a mating connector.

摘要： A power converter including a transformer, a resonant circuit including the transformer and a resonant capacitor having a characteristic resonant frequency and period, and output circuitry connected to the transformer for delivering a rectified output voltage to a load. Primary switches drive the resonant circuit, a switch controller operates the primary switches in a series of converter operating cycles which include power transfer intervals of adjustable duration during which a resonant current at the characteristic resonant frequency flows through a winding of the transformer. The operating cycles may also include energy recycling intervals of variable duration for charging and discharging capacitances within the converter. A gate driver includes a transformer, a plurality of switches, a current monitor, and a controller that operates the switches in a series of driver operating cycles having adjustable ON periods and adjustable transition periods during which capacitances are resonantly charged and discharged.

摘要： A power converter system converts power from an input source for delivery to an active load. An input current surge at startup may be reduced by combining power converter switch resistance modulation with active load control. In another aspect, an input current surge at startup in an array of power converters may be reduced by periodically reconfiguring the array during the startup phase to accumulatively increase the output voltage up to a predetermined output voltage. A power converter may include a controller that provides an over-current signal to the load to reduce the load or advise of potential voltage perturbations.

摘要： Electronic modules having complex contact structures may be formed by encapsulating panels containing pluralities of electronic modules delineated by cut lines and having conductive interconnects buried within the panel along the cut lines. Holes defining contact regions along the electronic module sidewall may be cut into the panel along the cut lines to expose the buried interconnects. The panel may be metallized, e.g. by a series or processes including plating, on selected surfaces including in the holes to form the contacts and other metal structures followed by cutting the panel along the cut lines to singulate the individual electronic models. The contacts may be located in a conductive grove providing a castellated module.
