    Outline

     

    Due to new technology being developed, GaN can effectively reduce switching losses, reverse conduction losses in PFC and increase power density as switching frequency is increased. However, with faster turn-on and turn-off of GaN, EMI issue has been one hot topic for PFC designers facing and challenging to solve. We will introduce some solutions to solve EMI issues.
