The Photovoltaic inverter power supply assembly inductor manufactured by Haoer supplier plays three core roles in the inverter, supporting the efficient conversion and grid connection of photovoltaic power:
Energy storage and energy conversion in the DC-AC inverter stage. The inductor acts as an energy storage component. When the switching tube is conducting, it stores electrical energy; when the switching tube is turned off, it releases the energy. It works in conjunction with the inverter bridge to convert the DC electricity output from the photovoltaic panel into AC electricity, ensuring stable output voltage and frequency.
The alternating current output by the grid-connected harmonic filtering inverter contains high-frequency harmonics. The combined inductor attenuates the harmonic signals through the differential mode filtering function, making the output current waveform close to a sine wave, meeting the grid-connected harmonic standards (such as GB/T 14549-2008); at the same time, through the common mode choke function, it suppresses the common mode interference between the inverter and the grid, avoiding the interference signal being fed back to the photovoltaic panel or the grid.
The output current of the photovoltaic panel with current smoothing and voltage stabilizing features is greatly affected by the intensity of light and fluctuates significantly. The combined inductor can smooth the current fluctuations, stabilize the input voltage of the inverter, prevent the sudden change of current from causing impact on the switching devices, and enhance the operational reliability of the inverter.
· High saturation current carrying capacity
By using iron-silicon-aluminum / amorphous alloy cores, the saturation flux density exceeds that of traditional ferrite cores, capable of withstanding the instantaneous large current impact of the photovoltaic system (peak current can reach 2-3 times the rated current), and the inductance value does not significantly decrease, suitable for the fluctuating characteristics of photovoltaic power.
· Wide frequency range with low loss, enhancing inverter efficiency
The working frequency ranges of Photovoltaic Inverter Power Supply Assembly Inductor from 10kHz to 50kHz (the mainstream frequency range for photovoltaic inverters), with extremely low core loss (iron loss) and winding loss (copper loss). The overall efficiency of the component is ≥ 99%, effectively reducing the energy consumption of the inverter and increasing the power generation of the photovoltaic power station.
· Strong adaptability to wide temperature ranges
The working temperature range covers -40℃ to +125℃, with the temperature coefficient of magnetic permeability being ≤ ±5%. Even in the outdoor environments of photovoltaic power stations exposed to high temperatures and severe cold, it can still maintain stable performance and meet the industrial-level reliability requirements.
· Anti-interference and Grid Compliance
The integrated filtering structure can simultaneously suppress common-mode/differential-mode interference, helping the inverter obtain the EMC certification for grid connection (such as TUV, CE, UL), and preventing interference signals from affecting the power grid and surrounding equipment.
· Modular design simplifies the development of inverters
Integrating multiple inductor functions reduces the number of internal components and wiring complexity in the inverter, shortens the development cycle, lowers the equipment failure rate, and simultaneously reduces the size of the inverter to adapt to the miniaturization trend of photovoltaic systems.
