Claim:
1. A multi-phase interleaved converter, comprising: n sub-circuits of phases configured to have inputs connected in parallel and outputs connected in parallel in order to convert a direct current (DC) or alternating current (AC) input voltage of one level into a DC or AC output voltage of another level; a current controller configured to: i) receive a current control command and a phase current value of a particular sub-circuit of a particular phase among the n sub-circuits of respective phases and ii) output a control signal for controlling the particular sub-circuit of the particular phase; a balancing controller configured to: i) receive phase current values of the n sub-circuits of the respective phases and the control signal output from the current controller and ii) adjust duty ratios of control signals applied to the other sub-circuits based on the received phase current values of the n sub-circuits of the respective phases and the received control signal of the current controller, and a phase shifter configured to shift the phase of a control signal output from the balancing controller, wherein the particular sub-circuit directly receives a control signal output through the balancing controller, and the other sub-circuits receive a control signal of which phase is shifted by the phase shifter.
