Methods and devices for increasing the voltage gain range of a dc-dc power converter

The present invention relates to circuits and methods for increasing the voltage gain range of a DC-DC power converter. In particular, the present invention relates to a DC-DC power converter (200) comprising: two multiplier stages (M1, M2), each comprising two capacitors, each capacitor respectively connected to a diode, said diodes being adapted to charge the capacitors with a voltage; at least two switching devices (S1, S2) arranged to interchangeably operate between the at least two multiplier stages (M1, M2), or arranged to selectively connect the at least two multiplier stages (Ml, M2) in series in a first mode of operation and to at least partly bypass one of the at least two multiplier stages (M2) in a second mode of operation, thereby increasing the voltage gain range of the DC-DC power converter.
