Product Introduction
LCL lters are very commonly used in the modern renewable energy industry, and can e ciently and economically ensure and improve the feed quality from energy sources to the grid. The lters are used for filtration of the switching frequency of the invertor. When reaching the target distortion level, the lters can save considerable costs. LCL lters are typically characterized by small loss, small size, light weight, and high capacitance.
Product Features
The advancement of the technology of the high power semiconductor switching device promotes the rapid development of the technology of power electronic converters, giving birth to various types of converters, such
as inverter power supplies, frequency converters, etc. And these converters have been widely used in various as inverter power supplies, frequency converters, etc. And these converters have been widely used in various fields all over the country. Three-phase voltage-type PWM recti ers have the functions of bidirectional power transmission and fast dynamic control response. Most PWM recti ers currently adopt IGBT as the power switch device, which can achieve very high switching frequency compared to the general switching frequency of 2kHz-15kHz. However, the high on/o frequency of power switch device will generate high order harmonics to be injected into the grid, thus causing harmonic pollution. In order to solve the problems encountered by LCL filters, we generally choose LCL lters. Smaller inductance and capacitance values can be selected for the LCL filters to achieve satisfactory filtering effects between one kilowatt to hundreds of kilowatts.
