Abstract:
      Based on the conventional situation that there are two pulse currents for charging and discharging in the resonant switched-capacitor converter within a switching cycle, this paper proposes a novel half step-down switched capacitor converter with constant current charging and resonant discharge. The number of resonant current pulses in the resonant capacitor is halved, which increases the current duty cycle and reduces the resistive loss. According to the laws of circuit resonance and energy conversion, the mathematical expressions of output voltage, average current of charging pulse and conversion efficiency are analyzed, and a simple new method to reduce the generation of sneak circuits has been obtained. This type of resonant switched-capacitor converter can regulate the voltage by frequency modulation in a certain range which is a small resonance inductance DC converter with high efficiency. The correctness of the circuit and its analysis has been verified by simulation and experiment in the end
