ABSTRACT:
A novel power conversion system includes an energy storage circuit including a plurality of capacitors forming multiple stages, wherein each of the multiple stages includes one or more of the capacitors; a charging circuit connected to the energy storage circuit and during a charging cycle charging the plurality of capacitors from a voltage source to a predetermined voltage; a circuit for inverting the polarity of the voltage across selected capacitors; and a discharging circuit connected to the energy storage circuit and during a discharging cycle extracting power from the plurality of connected capacitors at a transformed voltage. The energy storage circuit further includes an interstage coupling circuit that provides interconnections interconnecting the capacitor stages. During the charging cycle, the interstage coupling circuit assumes one of two modes and during the discharging cycle, it assumes the other of the two modes. In the first mode, the interconnections have low impedance and in the second mode, the interconnections have high impedance.
