N2 - Multiphase dc-dc converters are widely used in power electronics. In the case of generating multiple output voltages from a common input voltage, converters have to operate at non-uniform duty cycles. This is challenging in regard to input current ripple minimization, as control techniques for interleaved operation of asymmetric converters are not well understood. In this paper, analytic formulas are derived to obtain uneven phase-shift angles for optimal ripple minimization. Simulations verify the performance of the proposed technique and compare it to conventional methods.
