Function：
In the inverter circuit, the main purpose is to smooth and filter the output voltage of the rectifier and store energy. It absorbs the high amplitude pulsating current from the inverter to the ‘DC-Link’, prevents it from generating high amplitude pulsating voltage on the impedance of the ‘DC-Link’, and keeps the voltage fluctuation on the DC bus within the permissible range. Voltage overshoot and transient overvoltage from the DC-Link are prevented from affecting the switching devices.
Areas of application：
New energy industry: photovoltaic inverter, wind power converter, etc. Energy-saving industry: high-voltage inverter, etc. Power supply industry: large high-frequency switching power supply, uninterruptible power supply (UPS), emergency power supply (EPS), intermediate frequency power supply, DC voltage stabilised power supply, electroplating power supply, chemical power supply and so on.
