Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Because the power supply system of the vehicle-mounted power amplifier in the prior art usually adopts a single-path power supply system based on a vehicle-mounted battery, the power supply system is directly connected between the vehicle-mounted battery and the vehicle-mounted power amplifier through the single-path power supply system, and the vehicle-mounted power amplifier is supplied with power through single-path power supply input. However, the resistance of the single-circuit power supply system is large, which results in a higher heat dissipation requirement of the power supply system of the vehicle-mounted power amplifier. Moreover, since the required current of the vehicle-mounted power amplifier is fixed, in order to meet the required current of the vehicle-mounted power amplifier, elements matched with the rated current need to be selected to build a single-path power supply system, which causes higher cost of each element adopted in the single-path power supply system and is not beneficial to the wide application of the single-path power supply system.
Therefore, the embodiment of the utility model provides a vehicle-mounted power amplifier power supply system, which aims to solve the problems of the vehicle-mounted power amplifier power supply system in the prior art.
The vehicle-mounted power amplifier power supply system provided by the embodiment of the utility model comprises at least two power supply circuits, wherein the power supply circuits are connected in parallel and are connected between a vehicle-mounted battery and a vehicle-mounted power amplifier, and each power supply circuit is used for supplying power to the vehicle-mounted power amplifier based on the vehicle-mounted battery.
Specifically, the vehicle-mounted power amplifier power supply system provided in the embodiment of the utility model is used for supplying power for a vehicle-mounted power amplifier. The vehicle-mounted power amplifier is an audio power amplifier in a vehicle-mounted audio and video system, and needs to be supplied with power through a vehicle-mounted power amplifier power supply system to ensure that the vehicle-mounted power amplifier can work normally.
Fig. 1 and fig. 2 are schematic structural diagrams of a vehicle-mounted power amplifier power supply system provided in an embodiment of the present invention. As shown in fig. 1, the power system of the vehicle power amplifier includes two power circuits, i.e., a first power circuit 1 and a second power circuit 2. As shown in fig. 2, the vehicle-mounted power amplifier power supply system further includes a third power supply circuit 3 in addition to the first power supply circuit 1 and the second power supply circuit 2.
It should be noted that, in the embodiment of the present invention, the number of the power circuits included in the vehicle-mounted power amplifier power supply system is not specifically limited, and is only two or more, and the following description will be given by taking only two power circuits, i.e., the first power circuit 1 and the second power circuit 2, included in the vehicle-mounted power discharge power supply system in fig. 1 as an example.
The first power circuit 1 and the second power circuit 2 are connected in parallel, and the first power circuit 1 and the second power circuit 2 are both connected between the vehicle-mounted battery 4 and the vehicle-mounted power amplifier 5. The first power supply circuit 1 and the second power supply circuit 2 are used for supplying power for a vehicle-mounted power amplifier 5 based on a vehicle-mounted battery 4. That is, the in-vehicle battery 4, the first power supply circuit 1, and the in-vehicle power amplifier 5 are connected in order, and the in-vehicle battery 4, the second power supply circuit 2, and the in-vehicle power amplifier 5 are connected in order. Because the first power circuit 1 and the second power circuit 2 are connected in parallel, the vehicle-mounted power amplifier 5 can supply power independently through the first power circuit 1, independently through the second power circuit 2, and jointly through the first power circuit 1 and the second power circuit 2. Therefore, even if any one of the first power circuit 1 and the second power circuit 2 fails, the vehicle-mounted power amplifier can be powered by the other power circuit, the output power of the vehicle-mounted power amplifier 5 can be limited only, the performance of the vehicle-mounted power amplifier 5 cannot be affected, and the normal operation of the vehicle-mounted power amplifier 5 can be ensured.
Because the power supply system comprises at least two power supply circuits, the resistance value of the whole power supply system can be reduced by connecting the power supply circuits in parallel, so that the heat generated by the power supply system during working is reduced, and the heat dissipation requirement of the power supply system can be reduced.
Because the cost of the element with large rated current is higher in general, the power supply system in the embodiment of the utility model comprises at least two power supply circuits, and the power supply circuits can be mutually shunted, so that each power supply circuit can adopt the element with smaller rated current, the specification requirement of each power supply circuit on the element is reduced, and the cost of the power supply system can be further reduced.
The vehicle-mounted power amplifier power supply system provided by the embodiment of the utility model comprises at least two power supply circuits, wherein the power supply circuits are connected in parallel, each power supply circuit is connected between a vehicle-mounted battery and a vehicle-mounted power amplifier, and each power supply circuit is used for supplying power to the vehicle-mounted power amplifier based on the vehicle-mounted battery. Under the condition that any power supply circuit has problems, the vehicle-mounted power amplifier can be supplied with power through another power supply circuit so as to ensure the normal work of the vehicle-mounted power amplifier. And because the power supply system comprises at least two power supply circuits connected in parallel, the resistance value of the whole power supply system can be reduced, so that the heat generated by the power supply system during working is reduced, the heat dissipation requirement of the power supply system is further reduced, the specification requirement of each power supply circuit on elements can be further reduced, and the cost of the power supply system can be further reduced.
