Benefits of technology
The present invention is a power system that converts AC input into output for use by a load. The system includes a signal conversion module that generates heat during operation. A cooling fan is used to prevent damage to the module, and the fan's speed is controlled based on the temperature sensor feedback. The technical effect of this invention is the efficient cooling of the signal conversion module, which prevents damage and allows for optimal performance.
Problems solved by technology
For example, many internal components have a significant temperature rise during operation and thus are required to be cooled.
This can be done with a fan, but the use of a fan to cool components has not been optimized.

Embodiment Construction
[0010]Exemplary embodiments of the invention will now be described below by reference to the attached Figures. The described exemplary embodiments are intended to assist the understanding of the invention, and are not intended to limit the scope of the invention in any way. Like reference numerals refer to like elements throughout.
[0011]FIG. 1 depicts an exemplary power supply 100 of the present invention which is capable of welding or cutting. The power supply 100 can have any general topology or structure and the topology shown in FIG. 1 is intended to be exemplary and not limiting as other topologies will also be within spirit or scope of the present invention. In the embodiment show, the system 100 has an inverter-type topology in which an AC input signal is provided to an input rectifier 101 which rectifies the AC signal. The rectified signal is then directed to a regulated circuit 103 which can be any one of a boost circuit, buck circuit or combined buck-boost circuit or an in...

Abstract
A welding or cutting power system having a signal conversion module, which receives an AC input signal and converts the AC input signal to an output signal. The output signal is output to a load. The signal conversion module comprises at least one component which increases in temperature during operation of the signal conversion module, and a cooling fan is used to cool the at least one component of the signal conversion module. A motor is coupled to the fan to operate said cooling fan. The power system also includes a temperature sensor, which senses a temperature of the at least one component and generates a temperature feedback signal. The system further includes a fan controller that controls a rotational speed of the fan based on at least the temperature feedback signal.
Description
BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]Devices, systems, and methods consistent with the invention relate to welding and cutting, and more specifically related to systems and methods for real-time adjustment and operation of a cooling fan in a welding or cutting system.[0003]2. Description of the Related Art[0004]As welding technology and applications have advanced so have the demands on welding and cutting power supplies. These increased demands require power supplies to provide increased power density and output power capabilities. With these demands come ever increasing demands on the internal components of the power supply. For example, many internal components have a significant temperature rise during operation and thus are required to be cooled. This can be done with a fan, but the use of a fan to cool components has not been optimized.BRIEF SUMMARY OF THE INVENTION[0005]An exemplary embodiment of the present invention is a welding or cutting power sy...
