AI Customer ServiceAbstract: This paper explores the large-signal and small-signal dynamics of a series-capacitor (SC) buck-type converter and introduces an optimal closed-loop control scheme to accommodate both the steady-state and transient modes.
Applying the charge balance principle for three times, through the three series capacitors, the current sharing strategy can be obtained. Then applying the inductor volt-second balance to get the constraint conditions of the four times voltage gain.
The two-phase series capacitor (SC) Boost converter is proposed in . By adding a capacitor to the adjacent phase in traditional two-phase parallel converter, automatic current-sharing can be realized in the limited duty cycle range of 0.5 to 1.
In a steady state, the total charge through the capacitor is equal to 0 in a switch period. Because of coupling capacitors in phases, the shared-current in phases can be realized through the charge balance principle for several times. Fig. 2 shows the current sharing principle mainly adopted in this paper.
The new control method merges a voltage-mode controller for the steady-state operation and a nonlinear, state-plane based transient-mode controller for load transients. A detailed principle of the operation of the SC-buck converter is provided and explained through an average-behavioral model and state-plane analysis.
Generally, the control method of multiphase parallel converter is the traditional average phase shift control, that is, each phase adopts the same switch frequency and duty cycle, and each phase is evenly displaced with 2 π /N phase-shifted.
