The power control components 4 are connected to the processing component 2 and electrically connected to the power supply component 13, and each power control component 4 includes a power control circuit 41 And a rectifier filter 42 connected with the power control circuit 41, and the power control circuit 41 is electrically connected with the power supply element 13, and the rectifier filter 42 is connected with the negative connector 11 and the positive connector 12 electrical connections; and

An output power sensing element 5 located in the device main body 1, the output power sensing element 5 will be electrically connected with the power control component 4, and connected with the processing element 2 information, the output power sensing element 5 of this embodiment Take voltage and current detectors as an example.

Through the above description, the structure of this technology can already be understood, and according to the corresponding cooperation of this structure, the advantage of automatically adjusting the power supply to make the power supply more stable can be achieved, and the detailed explanation will be in Instructions below.

When the user needs to weld, if not in use, the user can place the negative electrode connector 11 and the positive electrode connector 12 separately. When welding is required, the negative electrode connector 11 and the positive electrode connector 12 can be connected to the main body of the device first. On the metal desktop, connect the negative connecting piece 11 and place the object to be welded 61 (this embodiment takes a metal sheet as an example), and connect the positive connecting piece 12 with a solder 62 (this embodiment takes a welding rod as an example).

Afterwards, power can be introduced into the device body 1 via the power supply element 13, and the power in the device body 1 will enter the power control components 4. At this time, the input power sensing element 3 will sense the state of the input power, and process The element 2 will perform an adjustment action according to the state of the input power. The adjustment method is to control the power control circuit 41 in each power control component 4 through the processing element 2 to adjust the current and voltage of the input power. In this embodiment, the power control circuit 41 is one of the H-bridge circuit, half-bridge circuit, or synchronous switching circuit, and the H-bridge circuit (or full-bridge structure circuit) is used as an example, but it is not limited, and the above-mentioned half-bridge circuit can also be used Bridge circuit or synchronous switching circuit, or multiple circuits connected in series, among which H bridge circuit (or full bridge structure circuit) is composed of multiple MOSFET (metal oxide semiconductor field effect transistor) electronic components, which can be used Adjust the voltage and current of the input power supply, and then convert the current into DC power that can be used by the negative connector 11 and the positive connector 12 through the rectification filter 42. Since the adjustment is performed through multiple sets of power control components 4, the adjustment effect It will be more stable, and because it directly controls and distributes the adjusted current directly through the processing element 2, it is more efficient in use. For example, the total input current is 500A (ampere), and the current required for output is 100A (ampere). In this embodiment, there are five groups of power control components 4, so each group will receive a current of 100A (ampere), and the output current of each group will be adjusted to 20A through a conversion ratio of 5 to 1, and the total output will be 100A. (Amps) of current.

At this time, the output power sensing element 5 will monitor the output in real time. The situation of the power supply is to make the processing element 2 adjust the regulation and control action of the power supply control circuit 41 in real time according to various situations. The output current will also increase significantly. At this time, the output power sensing element 5 will transmit this data to the processing element 2, and the processing element 2 will control the power control circuit 41 to change the conversion ratio, so that the output current can be stable and stable. Will not change arbitrarily, for example, when the total input current suddenly increases to 700A (ampere), if the power control circuit If the conversion ratio of 41 does not change, the total output current will increase to 140A (ampere), so at this time the processing element 2 will control the power supply control circuit 41 to adjust the conversion ratio to 7:1, so as to keep the total output current still It can be maintained at 100A (ampere) to achieve the effect of stable current. And because this case uses this kind of parallel power control component 4, it is possible to stably connect and use a battery with a large current, so as to improve the overall convenience of use.
