Increased PFC power efficiency by GaN, coming EMI issues and solutions
Experience:Rohm semi Ltd, Arrow electronics, Centillium communication semi
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.
