The car inverter circuit board is the core component of the vehicle inverter. The main function is to convert 12V DC to 220V AC power for vehicle appliances.

It is usually composed of inverter modules, control circuit boards and cases. Among them, the inverter module is the core component that realizes DC AC conversion, which consists of semiconductor switching device, magnetic material, capacitance and other components; control circuit boards are responsible for controlling the working process of the inverter module, including input and output protection, inverters Drives, fault diagnosis and other functions; shells play a role in protecting the circuit board and heat dissipation.

The design ideas of the car inverter are usually based on basic knowledge such as switching power supply circuit technology, and the design of the inverter is used to achieve a secondary inverter. The main idea is: use the switching power supply chip (such as TL494 and SG3525A, etc.), first increase the 12V DC power supply to a high -frequency AC power of 320V/50Hz, and then pass the high -frequency AC electricity to high voltage DC power through rectification, and then use sine wave pulse modulation method to control the turnover of the switch tube through the output pulse.

In the design of the car inverter, the stability, reliability, and safety of the circuit need to be considered. For example, add compensation resistance to the circuit to improve the problem of unstable oscillating frequency caused by changes in the power supply voltage; use different types of semiconductor switching devices, magnetic materials, capacitors and other components to improve the efficiency, output power and reliability of inverters; at the same time, problems such as heat dissipation performance and protection level must be considered in the design of the shell.

In short, the design of the car inverter needs to comprehensively consider various factors, including functional requirements, circuit principles, component selection, manufacturing process, etc. to ensure the performance and quality of the product.
