Patent number: 8885308Abstract: Control circuitry handles inrush current, and may provide under voltage and/or over voltage monitoring and handling, as well as remote enable handling. The circuitry may advantageously employ a sense capacitor in parallel with an input capacitor (e.g., bulk input filter capacitor), and a current mirror to produce a signal proportional to input current. A clamp circuit may control a series pass device to regulate current in response to the proportional signal, or to interrupt current flow in response to an under voltage or over voltage condition or receipt of a signal indicative of a disable state. An enable signal may be summed into a comparator that handles under voltage condition determination.Type: GrantFiled: July 18, 2011Date of Patent: November 11, 2014Assignee: Crane Electronics, Inc.Inventors: Barry F. Waltman, Rodney Alan Hughes, Reid Adriance, Bertrand Nkei, Jay Allen Kuehny

Patent number: 8866551Abstract: A dual compensation operational amplifier is suitable for use in an environment that experiences fluctuations in ambient energy levels. A dual compensation impedance can be determined to nullify or compensate for effects of an input offset voltage or an input bias current or both. Adjustments to the dual compensation impedance can be made based on calibration data for various environmental conditions so that the dual compensation impedance can be either pre-set for anticipated conditions in different target operational environments, or automatically adjusted in-situ. Target operational environments that may benefit from such a dual compensation impedance include remote areas that experience extreme or variable temperatures, high altitudes, space, or high radiation environments.Type: GrantFiled: September 10, 2012Date of Patent: October 21, 2014Assignee: Crane Electronics, Inc.Inventors: Cuon Lam, Jay Kuehny, David Perchlik

Patent number: 8829868Abstract: A power converter provides current limit/current share functionality, allowing use in a point-of-load architecture and/or in parallel with one or more other power converters. An inner current control loop may sense output current over only a portion of a duty cycle, for example at a low side active switch. The resulting signal is compensated, and may be level shifted, for example via a resistor divider network, and supplied to a current control amplifier. An outer voltage control loop may sense output voltage, and provide a voltage error signal from a voltage error amplifier to the resistor divider network. Power converters are operable as masters or slaves, and include sense input and trim input terminals.Type: GrantFiled: July 18, 2011Date of Patent: September 9, 2014Assignee: Crane Electronics, Inc.Inventors: Barry F. Waltman, Reid Adriance, Jay Allen Kuehny, Stefan Jon Kristjansson

Patent number: 8824167Abstract: An auxiliary power supply or bias voltage supply employs a step up switch mode DC/DC power converter topology to supply regulated bias supply voltages, from very low input voltages (e.g., less than 2V). The supply will synchronize to dynamic loads making it particularly useful in circuits with periodic high peak current power demands, for example, gate drive circuits employed in regulated switched mode power converters. When unladed, the supply will efficiently adjust its cycle period to the minimum required to maintain the desired boosted output voltage. Additional transformer windings or a charge pump may be used to generate additional vias voltage sources.Type: GrantFiled: July 18, 2011Date of Patent: September 2, 2014Assignee: Crane Electronics, Inc.Inventors: Rodney Alan Hughes, Reid Adriance, Bertrand Nkei, Jay Allen Kuehny

Patent number: 8710820Abstract: A power architecture receives an input signal at an input node and converts the input signal into an intermediate signal with a power conversion stage. The power conversion stage supplies the intermediate signal to an output node of the power conversion stage where the intermediate signal is filtered with an operating capacitance coupled to the output node. A hold-up capacitance is charged, and when a loss of the input signal is detected, the hold-up capacitance is coupled to the input node.Type: GrantFiled: March 31, 2010Date of Patent: April 29, 2014Assignee: Crane Electronics, Inc.Inventor: Ernest Clyde Parker

Publication number: 20140016356Abstract: A power converter has a transformer having three primary windings configured to receive respective phases of a three-phase alternating current (AC) input signal in a delta configuration and three secondary windings, each split into two portions, wherein the portions are coupled together in a regular hexagon. The power converter includes a rectifier having a first rectifier path coupled between taps of the secondary windings and a positive output of the power converter and a second rectifier path coupled between taps of the secondary windings and a negative output. One of the secondary windings may be reversed with respect to the other secondary windings. The primary windings may be split with a corresponding secondary winding sandwiched between portions of the primary. One of the paths may have a different inductance than the other path.Type: ApplicationFiled: February 24, 2012Publication date: January 16, 2014Applicant: CRANE ELECTRONICS, INC.Inventors: Kaz Furmanczyk, Randy Stephenson

Publication number: 20130010399Abstract: A transformer may include a first and a second continuous single piece multi-turn helical winding, one concentrically received by the other. The turns of the windings are electrically insulated from one another and spaced sufficiently close together to permit inductive coupling therebetween.

The single piece multi-turn helical windings may have a continuous or smooth radius of curvature, with no discontinuities or singularities between first and second end terminals. The transformer may be formed by wrapping electrical conductor about a winding form. The transformer may be used in various electrical circuits, for example converter circuits.Type: ApplicationFiled: September 7, 2012Publication date: January 10, 2013Applicant: Crane Electronics, Inc.Inventors: Christopher Dziubek, David Perchlik, Jay Kuehny
