Condensation on traffic mirrors in winter makes it difficult to check safety. As a solution, we proposed an anti-condensation system that heats the mirror surface using induction heating with high power efficiency, utilizing daytime charging energy. A design method was proposed, and the design error was less than 10.8%. Induction heating coils were selected, and Litz wire coils were found to be optimal. A prototype self-excited oscillation circuit was fabricated and its performance was evaluated.
