With the development of the economy, the era of one car per person has arrived. After having a car, a trip that says go away is no longer the slogan of a few people, but the choice of more people. In this era where everything can be "mobile". Office, communication, and entertainment can all be carried out in a mobile state. You need a magic box, especially when you want to use your home appliances outdoors. The car inverter appears. With it, you can a lot of things outside just like at home. Rice cookers, hair dryers, computers, and small refrigerators can all be used. Therefore, the car inverter, as a DC-to-AC converter used in mobile devices, will bring you a lot of convenience. Today we will introduce the function of a car power inverter to you.
The function of a car power inverter
The role of the automotive solar inverter is to give full play to the function of solar cell performance and system fault protection. It is an electronic device that converts low voltage DC into 220 volts of alternating current. The automotive inverter has these functions: the car inverter not only has the function of DC to AC conversion but also has the function of maximizing the performance of the solar cell and the function of system fault protection. To sum up, there are automatic operation and shutdown function, maximum power tracking control function, anti-independent operation function (for grid-connected system), automatic voltage adjustment function (for grid-connected system), DC detection function (for grid-connected system), DC grounding detection Function (for grid-connected systems). Here we briefly introduce the automatic operation and shutdown function and the maximum power tracking control function.
Automatic run and stop functions
After sunrise in the morning, the intensity of solar radiation increases gradually. The output of the solar cell also increases accordingly. When the output power required for car inverter operation is reached, the car inverter will automatically start running. After entering into operation, the car inverter monitors the output of the solar cell module all the time.
As long as the output power of the solar cell module is greater than the output power required for the inverter to work. The car inverter will continue to run until the sunset stops. Even in rainy days, the car inverter can run. When the output of the solar cell module becomes smaller and the output of the car inverter is close to 0, the car inverter will form a standby state. That is exactly the automatic run and stop functions of the car inverter.
Maximum power tracking control function
The output of the solar cell module varies with the intensity of solar radiation and the temperature of the solar cell module itself (chip temperature). In addition, since the solar cell module has the characteristic that the voltage decreases as the current increases, there is an optimal operating point where the maximum power can be obtained. The intensity of solar radiation is changing, and obviously, the optimal working point is also changing.
Relative to these changes, the operating point of the solar cell module is always at the maximum power point, and the system always obtains the maximum power output from the solar cell module. This control is a maximum power tracking control. The biggest feature of car inverters for solar power systems is that they include the function of maximum power point tracking (MPPT). Therefore, that is the maximum power-tracking control function of the car inverter.
The above is our brief introduction to the function of the car inverter. The automatic operation and shutdown functions of the car inverter and the maximum power tracking control function are introduced. These two functions are the most prominent functions of the car. We hope you can make better use of your car inverter after understanding the functions of the car inverter.
