In this configuration, the resonant capacitor is split into two capacitors. The equivalent resonant capacitance is the sum of the two capacitances. Both of the resonant capacitors carry a DC offset equal to half of the output voltage. The output capacitor gets energy for each half of the switching cycle. The output capacitor Cout still needs to be much larger (> 10 times) than the resonant capacitor. Or in other words, the output capacitor Cout can be considered as a high-frequency short at the switching frequency
