Parallel and separate inverter ADAU1701JSTZ-RL It is a power conversion device that converts DC electric energy into AC electric energy. It usually consists of inverter and power separator. The inverter is responsible for converting DC power into AC power, and the power separator is used to isolate the power connection between the inverter and the grid.
The working principle of the parallel inverter is as follows:
1. Inverter:
a. Input filtering: the parallel inverter first filters the input current through the input filter to remove high-frequency noise and harmonics in the current.
b. DC to DC conversion: then, the inverter converts the voltage of the DC power supply into the voltage matching the AC power grid, and controls the output voltage and frequency through PWM (pulse width modulation) technology.
c. Inverter control: the inverter adjusts the output voltage and frequency through the controller to meet the demand of the power grid. The controller usually uses a microprocessor to monitor and control the operating state of the inverter.
2. Power separator part:
a. Input protection: the power separator is used to isolate the power connection between the inverter and the power grid, and provide the protection function of input voltage and current.
b. DC to AC conversion: the power separator converts the AC power output by the inverter into the voltage and frequency matching the grid, and filters the output current through the output filter to ensure that the output current meets the load requirements of the grid.
The working process of parallel inverter is as follows:
1. The inverter part converts the voltage of DC power supply into AC voltage, and controls the output voltage and frequency through PWM technology.
2. The controller monitors and regulates the output of the inverter to ensure that the output voltage and frequency match the power grid.
3. The power separator isolates the power connection between the inverter and the power grid, and converts the AC power output by the inverter into the voltage and frequency matching the power grid.
4. The output filter filters the output current to ensure that the output current meets the load requirements of the power grid.
The parallel inverter has a wide range of applications. It is commonly used in solar power generation systems, wind power generation systems, electric vehicle charging piles and other scenarios to convert DC electric energy into AC electric energy and inject it into the power grid. It has the advantages of high efficiency, good stability and high reliability, which is of great significance for improving energy utilization efficiency and reducing dependence on fossil fuels.
