Inverter DC Link Capacitor Selection
In a VSI, the DC link capacitor has two main responsibilities – Provide low impedance path for high frequency currents – As frequency goes up, the battery and cable parasitic inductance cause the impedance to increase. The DC link capacitor impedance goes down so it becomes the preferable path for high frequency AC to circulate.
