High-voltage DC capacitors are designed to handle and store significant amounts of direct current (DC) voltage, making them crucial for applications requiring stable, efficient energy storage and regulation. Our range of high-voltage DC capacitors provides superior performance, with robust construction.
The DC link is a critical component for high-power inverters utilizing fast switching that is often overlooked during the initial stages of design. The DC-link capacitor draws a continuous low-frequency current from the DC source while supplying the charge needed for the fast switching events and effectively functions as a charge pump.
The first step in sizing capacitors for inverter bus link applications should be to understand how much bus link capacitance is required for a given inverter design. The biggest design limitation for electrolytic capacitors in inverter applications has been the amount of ripple current that the electrolytic capacitor can sustain.
We may infer from Figure 2 that the DC link capacitor’s AC ripple current Icap arises from two main contributors: (1) the incoming current from the energy source and (2) the current drawn by the inverter. Capacitors cannot pass DC current; thus, DC current only flows from the source to the inverter, bypassing the capacitor.
