Metallized Polypropylene Film Capacitors For example, consider two of the main purposes of capacitors in electric vehicles: to prevent ripple currents from reaching back to the power source, and to smooth out DC bus voltage variations. Capacitors are also vital in protecting semiconductors – originally thyristors, but now usually IGBTs.

In applications in which energy conservation is critical, such as wind or solar inverters or electric-vehicle (EV) powertrains, distributing power at high voltage can help to reduce I2R losses. The DC link supplying the inverter can be 3 V to 400 V in an EV application, for example, or even higher for wind or solar-power conditioning. However, high operating voltages like these bring additional safety challenges not only for end users but also for components — even those with a suitable voltage rating stamped on the case.
