    For low current needs (half the rating of the transformer or less)

    1. Use a full wave rectifier circuit with a 1:1 isolation transformer.

    2. Use a voltage doubler rectifier circuit with a 220 to 110 step down transformer.

    For high current needs the transformers become insanely large and expensive. Best cost choice for intermittent, high current DC needs is battery
