20100067260 | POWER SUPPLY - In a switched mode power supply, and in accordance with a method for operating a switched mode power supply, the magnitude of each occurrence of a current flowing during operation of a power output switch is sensed for negative feedback control. A sense voltage is generated proportional to the primary supply voltage. Whenever the sense voltage exceeds a threshold, output power of the power supply is limited by increasing the sensed magnitude of each occurrence of the flowing currents by adding to each sensed magnitude a voltage proportional to the sense voltage. Threshold voltages can be selected by using Zener diodes having different breakdown voltages. Respective ranges within the overall range of the primary supply voltage in which supplemental power limiting occurs and does not occur can thus be controlled. | 03-18-2010 |

20100308875 | SWITCHABLE LOAD FOR INITIALIZING AN OUTPUT VOLTAGE OF A POWER SUPPLY - A conductive transistor switch has a collector that applies a reset pulse to an electronic circuit. A pull-up resistor is coupled between the collector of the transistor switch and a power supply voltage developed in a filter capacitor that energizes the electronic circuit. Proper reset operation requires the output supply voltage not to exceed, for example, 0.2 volts, during at least a portion of the reset operation. The user initiates the reset pulse that momentarily disables a power supply for ceasing the generation of the output supply voltage when the reset operation is performed. The value of the resistor is selected to be sufficiently low such that when the transistor switch is conductive, the discharge of the filter capacitor via the pull-up resistor is speeded up for completing the discharge of the filter capacitor in no more than, for example, 2 seconds to provide a maximum level of the output supply voltage that is no more than 5% of its normal operation voltage level. | 12-09-2010 |
20120287689 | SYNCHRONOUS RECTIFIER DISABLING ARRANGEMENT - A power supply receives an alternating current input that is rectified by a rectifier. The rectified output voltage is coupled to a load and a microprocessor during both a run mode operation and a standby mode operation. The rectifier provides synchronous rectification by an included MOSFET, during the run mode operation and non-synchronous rectification during the standby mode operation by an included Schottky diode. The Schottky diode in rectifier is in parallel with the MOSFET and provides rectification during the standby mode operation. A source of an on/off control signal from the microprocessor is applied to the load for changing the operation mode and applied, in parallel, to the rectifier for disabling the synchronous rectification in the rectifier, during the standby mode operation. The efficiency of the power supply is improved in the standby mode operation by elimination of the power consumed to energize a synchronous rectifier controller. The efficiency of the power supply is also improved in the standby mode operation by using the on/off control signal from the microprocessor to disable the synchronous operation. | 11-15-2012 |
