Three-phase choke for high power density sine-wave filter cooling WF
Three-phase choke for high power density sine-wave filter cooling WF
Description
Primary choke for liquid-cooled WF converter output LC filter. Allows to reduce the integration size in the converter. They attenuate PWM switching harmonics by restoring the sine wave and at the same time eliminate the problems associated with high dV/dt.
