Charger mainboard test equipment for simulating Qi standard wireless charging by using real coil

Abstract

The invention provides charger mainboard test equipment for simulating Qi standard wireless charging by using a real coil, and the equipment is low in cost, high in integration level, complete in function and is suitable for a product manufacturing whole-process test. The equipment comprises a power supply module (1), a transmitting and receiving coil (2), an electronic simulation load (3), an FPGA (4), a plurality of function test modules, a high-speed ADC acquisition module (5) and a peripheral upper computer (6). The power supply module powers up the whole test equipment and a charger mainboard (7) to be tested. One side of the transmitting and receiving coil is connected with the charger mainboard to be tested, the other side is connected with the electronic simulation load, the high-speed ADC acquisition module acquires various signals of the charger mainboard to be tested and uploads the signals to the FPGA, and the function test modules perform function test on the simulated output process of the charger mainboard to be tested, output a test result to the FPGA for analysis, and upload the test result to the upper computer for background processing and storage. The equipmentis applied to the field of wireless charger testing.

Description

technical field [0001] The invention relates to the field of wireless charger testing, in particular to a charger main board testing device which uses real coils to simulate Qi standard wireless charging. Background technique [0002] With the extensive development of network communication and electronic digital, people's dependence on electronic products is increasing day by day. However, the battery capacity is far from keeping up with the demand for electricity, and wireless charging is an emerging technology that can most lead the electric revolution. It is very different from traditional charging technology. It charges electronic equipment through wireless energy transmission, and separates the physical connection between the power supply equipment and the electrical equipment, so that while improving the beauty and practicability of the electrical equipment, it can also improve the safety of the electrical equipment. Qi is the world's first standardization organizati...

AI Technical Summary

Problems solved by technology

[0004] The traditional method generally uses a standard power supply, electronic load, and some self-made modules to form a test system, which is bulky and expensive, and can only test basic functions such as efficiency and heat generation, and cannot test more functions. In particular, it is impossible to test functions such as charging and communication during the design stage of the charger circuit board, so that the defects generated in the circuit board design stage cannot be found until the later detection process after the charger is completed, which leads to the failure to guarantee product quality and also Increased scrap rate, resulting in higher costs and waste of resources
