fully discharged from supply voltage v in to a diode drop or virtually 0v the current waveform flowing through the loading will have a similar waveform as in period between t 1 and t 2 except for opposite polarity also the load current waveform will be similar to that in period between t 2 and t 3 but with opposite polarity the circuit will deliver an averaged power p op to output loading at a switching frequency fs with the following relationship p op c 101a c 101b fsv in 2 equation 6 with corresponding equivalent averaged input resistance r in u2014 eq of it should be noticed that the output power and the equivalent input resistance is dependent on the sum of the two series capacitor c 101a and c 101b it means the two capacitances do not need to be equal or even when one is omit to simplified design it does not affect the operation and characteristic of the operation also the output power and input equivalent is linearly proportional to frequency with no restriction hence one can adjust the output power and input equivalent resistance by adjusting the frequency unlike generic practice the series inductor l 101 is not used to create a series resonance in order to pump and limit the energy to.
