Abstract
An illustrative current-doubling DC-DC conversion method includes: converting an input voltage into forward voltage pulses and reverse voltage pulses on a primary of a transformer having a secondary coupled between a drive terminal of a first inductor and a drive terminal of a second inductor, the first and second inductors each having a common terminal coupled to a first output voltage terminal; selectively coupling the first inductor's drive terminal to a charge terminal of a reserve capacitor or to a second output voltage terminal, the first inductor's drive terminal being coupled to the charge terminal at least during the forward voltage pulses; selectively coupling the second inductor's drive terminal to the charge terminal of the reserve capacitor or to the second output voltage terminal, the second inductor's drive terminal being coupled to the charge terminal at least during the reverse voltage pulses; and concurrently coupling the drive terminals of the first and second inductors to the charge terminal to concurrently boost current flow through the first and second inductors in response to a load transient.
