Description

Technical Field

[0001] This application relates to the field of resistive load technology, and more specifically, to a circuit that makes the resistive load the same under two multiples of voltage power. Background Technology

[0002] In current electronic device and system design, power matching of resistive loads is a crucial consideration. Especially in scenarios requiring adaptation to different voltage inputs, ensuring that the resistive load maintains the same power output under varying voltage conditions has become a significant technical challenge.

[0003] Traditional solutions typically rely on adding additional resistive loads to achieve power balance. While this approach addresses the problem to some extent, it introduces significant drawbacks. First, increasing resistive loads requires more physical space to install these components, a considerable challenge for modern electronic devices striving for miniaturization and compactness. Second, additional resistive loads not only increase material costs but may also lead to higher overall energy consumption, thus reducing the device's energy efficiency ratio. Finally, this design approach hinders the improvement of power density, i.e., power output per unit volume or weight, which impedes the development of high-performance, high-efficiency electronic devices.

[0004] Existing methods for achieving the same power output for resistive loads under two different voltages suffer from drawbacks such as large space requirements, high costs, and low power density. Therefore, there is an urgent need for an innovative circuit design that can effectively achieve power matching of resistive loads under different voltage conditions without adding additional resistive loads, thereby improving the overall performance and competitiveness of the equipment. Utility Model Content

[0005] Based on the above problems, this application proposes a circuit that makes the resistive load the same under two multiples of voltage power, in order to solve the technical problems of existing equipment having large internal space requirements, high cost, and low power density.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A circuit that makes the resistive load the same under two multiples of voltage power includes a power supply, to which a first resistor and a second contactor are connected by a line, to which a third contactor and a first contactor are connected by a line, and a second resistor is connected between the first contactor and the second contactor.

[0008] In one specific implementation, the first contactor, the second contactor, and the third contactor use the same rules and model.

[0009] In one specific implementation, the first resistor and the second resistor have the same resistance value.

[0010] In one specific implementation, the second resistor and the third contactor form a series circuit, which is connected in parallel with the circuit formed by the first resistor and the second contactor.

[0011] In one specific implementation, one end of the first contactor is electrically connected to the circuit consisting of the first resistor and the second contactor, and the other end is electrically connected to the circuit consisting of the second resistor and the third contactor connected in series.

[0012] In one specific implementation, the electrical connection point of the first contactor is between the first resistor and the second contactor, and the other electrical connection point is between the second resistor and the third contactor.

[0013] The positive effects of this utility model are:

[0014] By combining contactors, power matching of resistive loads under different voltages is achieved without the need for additional resistive loads and complex circuit designs, thus simplifying the overall structure of the equipment and reducing design difficulty and manufacturing costs.

[0015] Since no additional resistive load is required, the circuit design of this application can make more efficient use of the internal space of the device and improve the power output capability per unit volume or weight, i.e., power density, which is of great significance for the development of high-performance and high-efficiency electronic devices.

[0016] By reducing the number of resistive loads and simplifying circuit design, this application can significantly reduce the material and manufacturing costs of the equipment, thereby improving its economic efficiency and market competitiveness.

[0017] Since the circuit design scheme of this application can keep the total power of the resistive load constant under different voltages, it avoids the problem of increased overall energy consumption caused by adding additional resistive load in the traditional method, and improves the energy efficiency ratio and energy utilization efficiency of the equipment.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0023] Example

[0024] like Figure 1 As shown, a circuit that makes the resistive load the same under two multiples of voltage power includes a power supply. A first resistor 1 and a second contactor 4 are connected to the power supply via a circuit. A third contactor 5 and a first contactor 3 are connected to the first resistor 1 via a circuit. A second resistor 2 is connected between the first contactor 3 and the second contactor 4. One end of the first contactor 3 is electrically connected to the circuit formed by the first resistor 1 and the second contactor 4, and the other end is electrically connected to the circuit formed by the second resistor 2 and the third contactor 5 connected in series.

[0025] The second resistor 2 and the third contactor 5 form a series circuit, and the series circuit formed by the second resistor 2 and the third contactor 5 is connected in parallel with the circuit formed by the first resistor 1 and the second contactor 4.

[0026] The electrical connection point of the first contactor 3 is between the first resistor 1 and the second contactor 4, and the other electrical connection point is between the second resistor 2 and the third contactor 5.

[0027] The first contactor 3, the second contactor 4, and the third contactor 5 adopt the same rules and model. Through the combined control of the contactors, power matching of the resistive load under different voltages is achieved without the need for additional resistive loads and complex circuit designs, thereby simplifying the overall structure of the equipment and reducing design difficulty and manufacturing costs.

[0028] The first resistor 1 and the second resistor 2 have the same resistance value. When the voltage is 2U, the first contactor 3 is closed, and the second contactor 4 and the third contactor 5 are open, connecting the first resistor 1 and the second resistor 2 in series. According to Ohm's law and the power calculation formula, the power P = 2U * 2U / (first resistor 1 + second resistor 2), therefore P1 = 4U. 2 / 2R=2U 2 / R.

[0029] When the voltage is U, the first contactor 3 is open, and the second contactor 4 and the third contactor 5 are closed. The first resistor 1 and the second resistor 2 are connected in parallel. At this time, according to Ohm's law and the power calculation formula, the power P = U * U / (1 / R1 + 1 / R2), where R1 and R2 have the same resistance, so P2 = U 2 / (R*1 / 2)=2U 2 / R. By reducing the number of resistive loads and simplifying circuit design, this structure can significantly reduce the material and manufacturing costs of the equipment, thereby improving its economic efficiency and market competitiveness.

[0030] This structure maintains a constant total power of the resistive load under different voltages, thus avoiding the increased overall energy consumption caused by adding additional resistive loads in traditional methods. This improves the energy efficiency ratio and energy utilization efficiency of the equipment. Two resistors of the same resistance value operate under two power supply voltages that are twice the rated voltage. By using three contactors to switch the series and parallel connections of the resistors, the same power of the resistors under the two voltages is achieved.

[0031] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
