摘要: Disclosed is a power supply module for use in an electronic system having redundant power supply modules connected to a power bus. The power supply module includes an output filter. The output filter is configured, upon insertion of the power supply module into the electronic system during operation of the electronic system, to limit reverse current flow into the power supply module from the power bus for a period of time until steady state voltage conditions exist on the power bus. The output filter is configured to then remove the current-limiting, leaving an output inductor-capacitor filter.

摘要: A power meter receives an output-voltage and a current-indicative signal generated by at least one power supply of an electronic system. The output voltage powers at least one electronic component of the electronic system. The current-indicative signal indicates a percentage of a maximum output current capacity at which the power supply is producing current. From the output voltage and the current-indicative signal, the power meter determines the input power received by the power supply.

摘要: A DC-to-DC converter comprises a first power module, at least a second power module coupled to the first power module, and a protection circuit coupled to the first and second power modules. The protection circuit causes a system power good signal to be at a state indicative of a power problem when the protection circuit detects that a switching node of one of the power modules has ceased switching.

摘要: The present invention relates to highly efficient suction and compression rotating mechanisms, particularly the compression mechanism with piston blocks mounted on two axes and driven by a pair of matching gears in the field of compressors and vacuums or hydraulic system such as oil pump, hydraulic motor, hydraulic gearbox, specifically there is application that uses this mechanism to create one rotary motor with multi compression stages, force-generating stages and continuous fuel burning regime. The new rotary lobe structure in this invention provides a close contact between curved surfaces with the same radius, which is a “Surface-to-surface” contact, with much better tightness than “line” contact.

摘要: A control circuit and method for controlling a power factor correction circuit comprising: an inductor having an input terminal to receive an input voltage and an output terminal series connected to an anode of a diode; a first capacitor connected between a cathode of said diode and ground; a first switch connected between an anode of said diode and ground; a series arrangement of a second capacitor and a parallel arrangement of a resistor and a second switch series connected with said second capacitor. The control circuit is operable to generate synchronous first and second switch control signals to respectively control said first and second switches, wherein during inrush current conditions when said input voltage drops-in after an interruption, said control circuit is operable to cause said first and second switches to be synchronously switched at increasing duty cycles. The method comprises charging a first capacitor from an input voltage source; isolating the first capacitor from the input voltage source; transferring a portion of charge stored in said first capacitor to a second capacitor while said input voltage source is isolated from said first capacitor and from said second capacitor; and repeatedly said charging, isolating, and transferring until a voltage is formed on said second capacitor that is approximately equal to said input voltage source.

摘要: A method and apparatus for planarizing a substrate are provided. A substrate carrier head with an improved cover for holding the substrate securely is provided. The cover may have a bead that is larger than the recess into which it fits, such that the compression forms a conformal seal inside the recess. The bead may also be left uncoated to enhance adhesion of the bead to the surface of the groove. The surface of the cover may be roughened to reduce adhesion of the substrate to the cover without using a non-stick coating.
