    Fast Generation of Planar Transformer Designs

    PI director of training, Andy Smith

       There is a drive to make almost all of our electronics smaller, including the power supplies and chargers. Often, it is only one individual component that is responsible for stopping further decreases in size, and in the case of power supplies, this component is usually the transformer. Wirewound tr
