Abstract
This disclosure describes modular, low-cost, high-efficiency, high power-density techniques to convert electrical power in a 2n:1 (n ≥ 2) ratio, e.g., 4:1, 6:1, 8:1, etc. The techniques are robust to component non-idealities over a wide range of operating conditions, and minimize current stress on components. The disclosed interleaved structure cancels input current ripple and thereby reduces the need for input-filtering capacitors. The switched tank converters find application in data centers, where DC-DC conversion is frequently required, e.g., from a bus voltage of forty-eight volts to an intermediate bus voltage of twelve or six volts.
