Main Functions
Support the output voltage of the rectifier in the inverter circuit to prevent voltage mutations, and filter out high-frequency ripples on the DC bus.
Smooth the high-amplitude pulsating current drawn by the inverter from the "DC-Link", prevent it from generating high-amplitude pulsating voltage across the impedance of the "DC-Link", and keep the voltage fluctuation on the DC bus within the allowable range.
Suppress voltage overshoot and transient overvoltage of the "DC-Link" to protect switching devices such as IGBTs.
