Inverter voltage selection

DC-Link Design Tips

The DC-Link capacitor must regulate voltage and absorb ripples in the current, as well. A ripple wiggles the level of the voltage that appears across the DC-Link capacitor while the switching current''s ripple travels through the capacitor (V=IR). One must also consider inverter switching frequencies that the DC-Link capacitor must tolerate.

Technical Explanation for Inverters

PWM control. The inverter outputs a pulsed voltage, and the pulses are smoothed by the motor coil so that a sine wave current flows to the motor to control the speed and torque of the motor. The voltage output from the inverter is in pulse form. The pulses are smoothed by the motor coil, and a sine wave current flows.

How to Select DC Link Capacitor

The capacitor is placed parallel to the battery, which maintains a solid voltage across the inverter. The device helps protect the inverter network from momentary voltage spikes, surges and EMI. The noise is the result of the pulsed inverter current and stray inductance on the DC bus [see Figure 2: Typical Electric Vehicle Circuit].
