Power Electronics
Power electronics are the most critical components in energy storage inverters and are primarily made of silicon and silicon carbide. Silicon power devices are stable, reliable, and simple in structure, but have relatively low efficiency. Silicon carbide power devices, on the other hand, offer high efficiency, low losses, and high-temperature tolerance, but are relatively expensive.
Conductive Sheet
Conductive sheet, also known as conductive foil, is the conductive element in energy storage inverters and is primarily made of copper, aluminum, and their alloys. With its high conductivity, corrosion resistance, and excellent conductive stability, conductive sheet is a key component for current transmission in energy storage inverters.
Capacitor
Capacitors are the energy storage elements in energy storage inverters and are primarily composed of aluminum electrolytic capacitors and silver capacitors. Aluminum electrolytic capacitors feature high capacitance, light weight, and compact size, making them suitable for high-capacity applications. Silver capacitors, however, are suitable for high-precision power systems due to their stable and controllable capacitance.
Reactors
Reactors are crucial components used to compensate for inductive elements in energy storage inverters. They are primarily composed of materials such as an iron core, coils, and windings. Reactors reduce harmonics, improve power factor, and enhance system stability, making them an essential component of energy storage inverter systems.
In summary, energy storage inverters, as crucial equipment in the new energy sector, are constructed from a wide variety of materials, each with varying properties and characteristics. Only by carefully selecting the right materials can energy storage inverters maximize their potential in the new energy sector.
