Though many an increasing number of people own a car and have many kinds of car accessories, among which is the most popular one – 1kW car power inverter, many of them know little about car accessories. It is convenient and powerful to use a power inverter when driving on the road. But people hardly know how it work, what functions it has or how it be used safely. To make more people know more about a power inverter and make full use of it in life, let’s discover how many functions it has and how much convenience it can bring to us.
Before talking about convenience it brings to us, let’s fist learn how much functions it has. To make this question clear, we need to know how many components a power inverter consists of.
Input interface
There are 3 interfaces which respectively transmit input signals of 12V DC current VIN, Enable Voltage ENB and Panel Current Control DIM. VIN is provided by adapter and ENB comes from MCU with 0V or 3V. When ENB is zero, the power inverter is off work and when it’s 3, the inverter is working normally. The main board provides DIM ranging from 0 to 5V. The lower a DIM is, the higher a power inverter will provide for loads.
PWM controller
The PWM controller controls DIM signals by receiving panel current and provide protection functions against overvoltage, low voltage, short circuit, pulse width modulation.
Direct current conversion circuit
When it receives DC 12V current and voltage called VIN, the MOS tube starts on and off functions so that the DC current can repeat charging and discharging to get alternating current.
LC vibration circuit
The LC vibration circuit ensures 1660V voltage the light tube needs when starts and then reduces it to 800V.
Feedback circuit
When the power inverter works normally, the feedback circuit can keep the current stable.
