Selection of the best capacitor for a power inverter or other DC link application usually begins with a comparison of the required capacitance and ripple currents. Make sure that the specs you are comparing are referenced to the same operational standards.
The DC link capacitor is applied from positive to negative after rectification. In a power inverter, a DC link capacitor is placed in parallel with the input to minimize the effects of voltage variations as the load changes. The DC link capacitor also provides a low-impedance path for ripple currents generated by power switching circuits.
New Bedford, MA 02744 January 12, 2015 Many of today’s inverter circuits require highly reliable and rugged capacitors to filter out the rich harmonic content of their AC output waveforms. The current of the harmonics at the output of inverter circuits is often greater than the current at the fundamental frequency.
Typically, aluminum electrolytic capacitors are the best option for power electronics applications requiring high capacitance (100’s of μF to Farads), up to 550 Vdc. current capacitor DC Link applications DC Link film caps meet bus voltage applications between 450 – 1300 Vdc. Custom DC Link designs available up
For three-phase inverters at any DC bus voltage, for films and electrolytics, respectively, a rule of thumb is that about 5 and 50 millicoulombs of capacitor nameplate CV rating will be required per amp of ripple current.
