DC-Link Capacitors

A DC-Link capacitor is an energy storage component that connects a rectifier and an inverter in power electronics circuits. It plays a crucial role in maintaining stable voltage, filtering electromagnetic interference (EMI), and absorbing current ripples for efficient operation. Found in variable frequency drives (VFD), electric vehicles (EVs), photovoltaic systems, and power inverters, DC-Link capacitors are key to stabilizing DC voltage and enabling the conversion from DC to AC power.
