Embodiment Construction

[0016] Reference will now be made in detail to example embodiments of the present disclosure, which are illustrated in the accompanying drawings. Whenever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0017] The aforementioned problems of designing and stocking large numbers of voltage attenuators when assembling power supplies with different voltages requiring attenuation can be overcome by one or more embodiments of the present invention. In one aspect, a printed circuit board may have mounted thereon a multi-tap voltage attenuator having a selectable plurality of input attenuator terminals for providing a desired attenuated output voltage. The multi-tap voltage attenuator can provide an appropriately attenuated output voltage based on, for example, the input voltage or output voltage of the power supply. The output of the multi-tap voltage attenuator may be coupled to a controller or other circuit device of ...

Abstract

A printed circuit board of a power supply has mounted thereon a multi-tap voltage attenuator which may provide a selectable number of input attenuator terminals. The power supply may comprise two or more of the same printed circuit board to attenuate different input and output supply voltages to substantially the same desired lower output voltage. The attenuated output voltage may be input to a controller, such as a power supply, to monitor and, if necessary, adjust one or more parameters of the output supply voltage. The selectable plurality of attenuated voltages allows the same or substantially the same printed circuit board to be used in the same and / or different power supplies for attenuating different voltages. Methods of assembling a power supply are also provided, as in other aspects.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims priority to US Provisional Patent Application No. 61 / 767,308, filed February 21, 2013, and entitled "Power Supplies Having Multi-Tap Voltage Attenuators And Methods Of Power Supply Assembly" (Attorney Signature 2012P21595US) , which is hereby incorporated by reference in its entirety for all purposes. technical field [0003] The present invention relates generally to power supplies, and more particularly, to power supplies having voltage attenuators. Background technique [0004] The power supply may have two or more voltage attenuators typically used to attenuate (ie reduce) the input voltage and output voltage of the power supply for use with the power supply's controller. Input voltage and output voltage can be attenuated to the same low voltage. The controller may monitor and, if necessary, adjust one or more parameters related to the input voltage and / or output voltage of the power supply...
